Answer:

Two other exponents that results in 256 are [tex]16^2[/tex] and [tex]4^4[/tex]

Step-by-step explanation:

Given

[tex]2^8 = 256[/tex]

Required

Write two exponential expression that equals 256

[tex]2^8 = 256[/tex]

Expand 8 as 4 * 2

[tex]2^{4*2} = 256[/tex]

Using laws of indices, we have

[tex](2^4)^2 = 256[/tex]

2⁴ = 16; So, we have

[tex]16^2 = 256[/tex] --- This is one

Recall that

[tex]2^{4*2} = 256[/tex]

This can also be rewritten as

[tex]2^{2*4} = 256[/tex]

Using laws of indices, we have

[tex](2^2)^4 = 256[/tex]

2² = 4; So, we have

[tex]4^4 = 256[/tex] --- This is another one

Hence, two other exponents that results in 256 are [tex]16^2[/tex] and [tex]4^4[/tex]
