You Can't get zero!!. Because sqrt(64) - 8=8 - 8=0. Now, your denominator is zero and you cannot divide, or are NOT allowed, to divide anything by zero!!. So, basically there "no solution" to your "x".

all a joke, but jimmy had 45 candy bars and ate forty, what does he have left?

not sure of the question asked, although 5^3 is 125. 5^3 means that you have the equivalant of (5x5x5) (or 3 fives multiplied by themselves.) It is simple work of 5x5 is = to 25, and 25 x 5 = 125. If you are having trouble wrapping your head around the multilplication or the idea as a whole, study the individual parts seperate, then come back with an open mind.

Hope This helped!

simply move the decimal point over the required ammount (laemans terms, the number of zeros in the multiplier.)

1,000,00,00 * 12.456

(if 1,000,00,00 is a typo, and you meant american billion, simply add two zeros to the end of the answer)

answer is 12,456,00,00.

the way that you recieve this answer is all whole numbers, you put the ones in the place of the one, you put the tens in the next decimal point (equal to 10,000,00,00), etc. you simply place the decimals with the zeros corrilating directly to the first zero from the 1 (in 1,000,00,00)

-1/6

**     Also can the answer -2 < x < 1 be explained?

ok you must understand this before you can possible understand the other bit.

This means that x has to be between -2 and +1

If you graphed it it would look like this

Clancy is right, most calcs do have such a button but the web2.0 calc does not. :(

say you have 4.678 hours this is what I would do.

4 hours

0.478*60 = 28.68        28 minutes

0.68*60 = 40.8  seconds

4.678 hours = 4 hours, 28 minutes and 40.8 seconds

amount of something : to something. like for instance i have 3 oranges and 2 apples, then ratio of ORANGE TO APPLES is 3:2 

Suppose you borrow $2000 today and are required to pay $2100 in 6 months. What is the simple interest rate?5%

If you are after the 6 roots of x^6 = -1 they are:

.

If you are unable to plot them then take the differences of successive y-values and divide by the corresponding differences of the x-values.  If the resulting values are all the same they represent a linear function, otherwise they represent a non-linear function.

sqrt(27a^9)  →  sqrt(9*3*a^8*a)  →  sqrt(3^2*(a^4)^2*3a)  →  3a^4*sqrt(3a)

yeah put it in the calucator

there is a button on the calucator that looks like 3 bubbles 1 commor,3 bubbles

That isn't a recursive formula, though you could arrange it as one, e.g., 

\(V_{n+1}\ =\ \frac 3 4 V_n \)

What type of calculator are you using?

Just input into a calculator dude...

I don't think you can necessarily put in equations into a handheld calculator, some specialized calculators on the web may help but other than that I can't say much.

5 points from me, HSC.....!!!!

Each orange takes up 4/3 as much volume as each pear

Thus....each orange can be considered as 4/3 of a pear

Therefore....if there already 28 pears in the basket, it could hold 12 more pears

But.......we could only have 9 more oranges in the basket because 9 (4/3)pears = 12 pears

My good sir Mr. Guest I believe I can help you with this situation.

You are given:

\(\sqrt{200}+\sqrt{18}\)

You have to find muliples of 200 and 18, separate them and try to find perfect squares like so:

\(\sqrt{4* 2 * 25} + \sqrt{9 * 2}\)

4, 25, and 9 can go on the outside of the square root giving you:

\(2*5\sqrt{2} + 3\sqrt{2}\)

I'm sure you can simplify.

I assume you have this :

√[20 q¹⁰ ]     ......if so   ..... this equates to....

(20 q¹⁰) ^1/2   =

√20  * q⁵  =

√[4 * 5] * q⁵  =

√4 * √5 * q⁵  =

2√5 q⁵
