The length of the carpet is 2a2 and width is 3a. Find the area of the carpet. HELP ME PLEASE

jenyasd209 [6]

Answer:

$6a^{3}$

Step-by-step explanation:This is a very simple question.

We all know that the equation or formula for area is...

A= L*W

So multiply...

$2a^{2} *3a$ = $6a^{3}$

Since 3a has an exponent power of 1 and you add the exponent power when multiplying...

The result would be... $6a^{3}$ .

Hope this helps:)

Why do whole numbers rise to an exponent get greater while fractions raise to an exponent get smaller?

erma4kov [3.2K]

Answer:

This is because exponents increase a number, for example $2, and, 2^2$ squaring a number is basically multiplying it by itself. So $2 * 2 = 2^2=4$ . Now obiviously 4 is greater than 2. But lets make the numbers like this:

$\frac{1}{2}, and, \frac{1}{2}^2$

And again, $\frac{1}{2}*\frac{1}{2} = (\frac{1}{2})^2 = \frac{1}{4}$

Now, which is bigger $\frac{1}{2}or\frac{1}{4}$

A quarter is smaller than a half right?

So in this case we can see that fractions raised to an exponent get smaller while numbers raised to an exponent get bigger.
