Question

PLZZZZZZ help with this

Answer 1

`28 {m}^(7) {n}^(5)`

Explanation:

14*2=28; m^2*m^5=m^7.

When you're working with multiplication of powers, you have to add the exponents. For example

`{x}^(4) * {x}^(2) = {x}^(6)`

Because

`{x}^(4) = x * x * x * x \\ {x}^(2) = x * x \\ {x}^(4) * {x}^(2) = x * x * x * x * x * x = {x}^(6)`

Answer 2

28m⁷n⁵

Explanation:

You would first multiply 14 by 2. You would then multiply (which is really addition when it comes to exponents) your like-term exponents.

(14m²n⁵)(2m⁵) =28m⁷n⁵

14(2) = 28

m² + m⁵=m⁷

n⁵ + 0 = n⁵
