Question

Simpify 3^2 times 3^5

Answer 1

Answer:  3^7

This is equivalent to 2187 if you were to evaluate 3^7 with a calculator.

============================================================

Explanation:

The rule you use is

$a^b*a^c = a^{b+c}$

When we multiply exponential expressions with the same base, we add the exponents. The base stays the same.

So,

$3^2*3^5 = 3^{2+5} = 3^7$

If the bases were different, then you cannot use this rule.

Answer 2

Answer:

Ok!

Step-by-step explanation:

So I’m guessing 3^2 means 3x3 basically! If I’m wrong pls correct! Anyways, so you wanna write the equation like so: (3^2) + (3^5). Next, do 3^2 which gets you 9. Then, do 3^5 which gets you 243. I know, it’s confusing haha. Now, add those two together & u get 252! There ya go, hoped it helped (:
