Question

What is the product

(3a^2b^7)(5a^3b^8)

Answer 1

option number 3

Explanation:

15a^ 5 b^ 15

Answer 2

15a^5b^15

Explanation:

There's a law of indices which states that when multiplying numbers, if they are the same, the power just add up.

So here 3a^2*5a^3 = 3*5a^2+3, which equals to 15a^5.

As for the b part of the terms, b^7*b^8 = b^7+8, which equals to b^15.

I hope this makes sense.
