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

Answer:

[tex]15^{3}[/tex] = 3375.

Step-by-step explanation:

Given  : [tex]f(x) = 15^{x}[/tex] for x =3.

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

Solution : We have given  [tex]f(x) = 15^{x}[/tex].

For x = 3.

Rule :  If [tex]a^{3} = a*a*a[/tex]

[tex]f(3) = 15^{3}[/tex]

Then  [tex]15^{3}[/tex] = 15*15*15.

[tex]15^{3}[/tex] = 3375.

Therefore, [tex]15^{3}[/tex] = 3375.
