Answer:
Two other exponents that results in 256 are
and

Explanation:
Given

Required
Write two exponential expression that equals 256

Expand 8 as 4 * 2

Using laws of indices, we have

2⁴ = 16; So, we have
--- This is one
Recall that

This can also be rewritten as

Using laws of indices, we have

2² = 4; So, we have
--- This is another one
Hence, two other exponents that results in 256 are
and
