since x is 3 you then type the equation like this 15^3 and multiply 15 three times

Answer:

\(15^{3}\) = 3375.

Step-by-step explanation:

Given  : \(f(x) = 15^{x}\) for x =3.

To find : evaluate the function rule for the given value.

Solution : We have given  \(f(x) = 15^{x}\).

For x = 3.

Rule :  If \(a^{3} = a*a*a\)

\(f(3) = 15^{3}\)

Then  \(15^{3}\) = 151515.

\(15^{3}\) = 3375.

Therefore, \(15^{3}\) = 3375.
