Question

Thanks for answering!!!

Answer 1

1. b⁵

2. +16m⁹

Explanation:

1. Add exponents: b³⁺² = b⁵

2. Negative and Negative = positive

2*8 = 16

m⁴⁺⁵ = m⁹

Hence: + 16m⁹

Answer 2

`1) \: {b}^(5)`

`2) \: \: + 16 {m}^(9)`

Explanation:

`{b}^(3) * {b}^(2) = {b}^(3 + 2) = {b}^(5)`

we know that

`( - ) *( - ) = ( + )`

So

`- 2 {m}^(4) * - 8 {m}^(5) \\ = + 16 {m}^(9)`
