Question

Please solve I’m confused

Answer 1

C

Explanation:

Applying the rule of exponents

`(a^m)^(n)` =
`a^(mn)`

note that

`a^(m)` ×
`a^(n)` =
`a^((m+n))`

Hence

`(2^3)^(1)` =
`2^(3(1))` =
`2^(3)` = 8

The classmate has mistakenly added the exponents to obtain

`(2^3)^(1)` =
`2^((3+1))` =
`2^(4)` = 16 ← incorrect

Answer 2

A. the proper steps that should have been taking would be to first would be to raise 2 to the power of 3, which would give you 8. Then raise it to the power of 1. So the most likely error is C. they added the exponents.
