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.
