Answer:
f(x) =
.
Explanation:
We are given functions
f(x) =
f(x) =
f(x) =
.
We need to find the function with simplified base of 4.
Let us simplify each of the function one by one.
On simplifying exponent in
, we get
.
On simplifying exponent in
we get 2^{4}.
On simplifying
we get
.
On simplifying
we get
Therefore, fourth function f(x) =
has simplified base 4.
