The answer is f(x) = 5(8)x or the letter D

Answer:

[tex]f(x)=5(8)^{x}[/tex]

Step-by-step explanation:

The given expression is [tex]f(x)=5(2)^{3x}[/tex]

So, to know what expression is equivalent, we just have to rewrite the given functions:

[tex]f(x)=5(2)^{3x}\\f(x)=5(2^{3})^{x}  \\f(x)=5(8)^{x}[/tex]

Therefore, the right answer is the last one:

[tex]f(x)=5(8)^{x}[/tex]
