Question

Thanks for answering!!!

Answer 1

Answer:

1. b⁵

2. +16m⁹

Step-by-step explanation:

1. Add exponents: b³⁺² = b⁵

2. Negative and Negative = positive

2*8 = 16

m⁴⁺⁵ = m⁹

Hence: + 16m⁹

Answer 2

Answer:

$1) \: {b}^{5}$

$2) \: \: + 16 {m}^{9}$

Step-by-step explanation:

${b}^{3} \times {b}^{2} = {b}^{3 + 2} = {b}^{5}$

we know that

$( - ) \times( - ) = ( + )$

So

$- 2 {m}^{4} \times - 8 {m}^{5} \\ = + 16 {m}^{9}$
