Question

Can someone pls help

Answer 1

b = 7

Explanation:

using the rule of exponents

`a^(m)` ×
`a^(n)` =
`a^((m+n))` , then

`(-14)^(8)` ×
`(-14)^(b)` =
`(-14)^(15)`

`(-14)^((8+b))` =
`(-14)^(15)`

since the bases on both sides are equal, both - 14, then equate exponents

8 + b = 15 ( subtract 8 from both sides )

b = 7
