To evaluate the expression, Evaluate the expression in the parentheses.

$$\left({\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{1}}\right) = {\mathtt{3}}$$

Now, do 3².

$${{\mathtt{3}}}^{{\mathtt{2}}} = {\mathtt{9}}$$

Now, divide.

$${\frac{{\mathtt{9}}}{{\mathtt{3}}}} = {\mathtt{3}}$$.

So, $${\mathtt{3}}$$ is the answer.

Hope it helps!

i think it is 3

4(a • b) = (4 • a)b is an example of which algebraic property?

We are basically distributing by grouping these differently, so it is the associative property of multiplication.

Find 2x - 3y - z if x = -3, y = 2, and z = -2

2(-3) - 3(2) - (-2) --> -6 - 6 + 2 -> -12 + 2= -10.

2x/3(y^-1) --> You can move the y^-1 on top --> 2xy/3.

What do we have to do with these x and y values?

-|-8+2| = -|-6| = -6.

To find the answer, change the fractions into whole numbers.

$$49\frac{1}{4}+3\frac{3}{8}\\\\=49\frac{2}{8}+3\frac{3}{8}$$ 

Now, add the whole numbers.

$${\mathtt{49}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}} = {\mathtt{52}}$$

Now, add the fractions.

$${\frac{{\mathtt{2}}}{{\mathtt{8}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{3}}}{{\mathtt{8}}}} = {\frac{{\mathtt{5}}}{{\mathtt{8}}}}$$

Now, combine the final answer of the fractions and whole numbers together and you get the answer $$52\frac{5}{8}$$.

$$\mbox{Final\;Answer}:\;52\frac{5}{8}$$

Hope it helps!

So, am I going to get my star back?

Don't panic DS!  The site seems to be undergoing a number of improvements/changes at the moment and peoples points have been going up and down like yoyos! 

Just grit your teeth and wait for everything to settle down!

I think thst it is 12 man inches that make a foot.

I don't like this update that much. It is getting me sick.

So, does this mean that my opinion's will be deleted? 

And will I go back to 85 points?!!?!?!?

Total horror.

Faint.

Where can you find the fun section? Or any section?

First, when we round whole numbers with decimals, we round to the nearest tenth.

So, we put the numbers below. Now, let's round.

So, the closest number is $${\mathtt{5\,386.7}}$$

Hope it helps!

Thanks to you, Melody. We can't do that much without you, Melody.

Thanks!

First, change $$1\frac{1}{2}$$ into a decimal.

$$1\frac{1}{2}=1.5$$

Now, multiply.

$${\mathtt{1.5}}{\mathtt{\,\times\,}}{\mathtt{2}} = {\mathtt{3}}$$

$$\mbox{So,\;3\;is\;the\;answer.}$$

Well, yes. I meant table. 

So, how do I make a table in @@LaTex?

(I always make a mistake when I say graph instead of table)

20,368^30.25= 22166069258430761966000000000000000000000000000000000000000000000000

000000000000000000000000000000000000000000000000000000000000000

And

5,500^17.15=14035249095304950000000000000000000000000000000000000000000000000

Thanks!

Just copy and paste these into the calculator on the home page here.

107 is a prime number so there isn't a simpler way of representing this, though you can get an approximate decimal representation as:

$${\mathtt{45}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{107}}}} = {\mathtt{465.483\: \!619\: \!475\: \!487\: \!021\: \!1}}$$

Area of a circle is given by $${\frac{{\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{diameter}}}^{{\mathtt{2}}}}{{\mathtt{4}}}}$$

You can plug your numbers into this formula using the calculator on the home page of this site.
