Hi CPhill,

Your correct answer is: $$2(3^5 -1 ) \textcolor[rgb]{1,0,0}{/} (3-1) = 242$$

It is equal to: $$s_n=\frac{a*(r^n-1)}{r-1}$$

here: $$s_5=\frac{2*(3^5-1)}{3-1}=242$$

Many Greetings

Wow kitty!

Good one Chris!

Hi Takahiro,

Thanks for that great answer,

Welcome to web2.0calc forum.

I have sent you a private message.

It a shortcut for raising 10 to a specified power

For instance

3.14 EE 12  =

3.14 X 10^12

The "10^x" button performs largely the same function.......

I have added these numbers to the number puzzle thread and directed people here for the answers.

1,2,3,4   Magic number is 22

Answers are here

You don't - I don't think so anyway.

What is an EE button?

Welcome to the forum isilber17.

I just sent you a private messages.

Before I answer this.

Pi is spelt like pi. 

Now, then, to the answer!

Pi is a irrational number. This means this number can not be expressed in a fraction. Usually what this means is that it is infinite!

In this case, Pi is infinite!~

Well... There isn't a easy way of doing this unless there are "Special Circumstances" but... Assuming that you don't know powers, I will briefly go through it.

Powers are simply the number of times the base number is multiplied by itself.
Confusing right..? >_<

For example. 3 to the power of 5 is equal to:

$${\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}} = {\mathtt{243}}$$

The Base number is 3 and the Index or the Power is 5.
This means 5 3's all multiplied together.!

Back to the question.

12 to the power of 27 is 

$${\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{12}} = {\mathtt{137\,370\,551\,967\,459\,378\,662\,586\,974\,208}}$$

Nice number eh...?

But don't do it this way!

Because the Base Number (12) is the same, we can use this special method.

In terms of Indicies, multiply is the equivalent to Plus.

For example:

4 to the power of 4 Multiplied by 4 to the power of 5 is equaled to 4 to the power of 9.

Do you see what i have done here..?

Now lets go back to the question.

12 to the 27 power * 12 to the -29 power 

Using the method I told you, you can just simplify it to just... 27+(-29)

This would equal to -2

Now substitute!

12 to the power of -2.

Now lets solve it!

$${{\mathtt{12}}}^{-{\mathtt{2}}} = {\frac{{\mathtt{1}}}{{\mathtt{144}}}} = {\mathtt{0.006\: \!944\: \!444\: \!444\: \!444\: \!4}}$$

Done!

REMEMBER, ONLY WORKS IF THE BASE IS THE SAME AS THE OTHER BASE!

I'm going to assume that the "missing" width is based on the Pytagorean Theorem and "a" is given by

SQRT (11.5^2 - 5^2) = about 10.36 ft.

However....it appears that your goal is extremely "non-standard" and I have have included a schematic of a more "normal" goal along with detailed instructions for its assembly.....

I figure you should be through puttng together all those little pieces at about the same time I finish helping Sisyphus with a little boulder "problem"......or thereabouts......

If I am interpreting the question correctly, I believe you are looking for perhaps the full number of 217.152302 Millions?

In this case, this question is easy. As Million is a unit, and you wish to convert it to a whole number, you will need to substitute a number for the unit "millions" In this case, it would be 1,000,000. So let us substitute!

$${\mathtt{217.152\: \!302}}{\mathtt{\,\times\,}}{\mathtt{1\,000\,000}}$$

Now, instead of going to that calculator beside you. Let me teach you a method. 

Because the number is disible by 10. You can use this special method.

Depending on now many 0's are in the number, you will need to move the . (Decimal Point) to the Right.
Lets use 1,000,000!

How many 0's are in there?

6?

I think so too!

Lets move the Decimal point to the right 6 times!

217.152302

to

217152302. (This is what it should look like)

Now, then we look at any number that ISN'T a 0 and multiply it by it.

In this case, it is a 1.

So...

$${\mathtt{217\,152\,302}}{\mathtt{\,\times\,}}{\mathtt{1}}$$

This would still equal to 217152302

Therefore, the answer you are looking for is 217152302

We need more detail if you want us to help.

Heureka explained a bit more LaTex.  I have been using it today and it works a treat!  Thanks Heureka.

I was thinking about giving you a thumbs down zegroes but CPhill's reply was too funny.

Just as well for you that the fossil is about or the dinosaur would eat you for breakfast!!!!!

It is easy to use.

Just click on it and then type in your question like you would an ordinary calculator the working and the answer will apear at the bottom of the screen and if you are happy press ok.

It's simple - have a play with it.

C = 2*pi*r

3.15 / (2*pi) = r ≈ .5013 cm

Considering how much you are on the forum you sure seem to miss a a lot of what is happening. haha

The hypotenuse of what?

Now come on! - you can see what the maximum is just as well as I can.

The median is the middle number (they have to be ordered first but these ones already are.)

The first quartile is the middle of the bottom half and, you guessed it, the upper quartile is the middle of the top half.

If there are 2 middle ones then you take the average of the 2.

Thanks Kitty,

A great answer - as always.

This will help you remember the formula
