To find \( f(3) \) using the function rule \( f(x) = 5(2)^x \), we substitute \( x = 3 \) into the equation.
\[
f(3) = 5(2)^3
\]
Now, calculate \( (2)^3 \):
\[
(2)^3 = 2 \times 2 \times 2 = 8
\]
Now substitute this back into the equation:
\[
f(3) = 5 \times 8 = 40
\]
Thus, the value of \( f(3) \) is \( \boxed{40} \).
\[
f(3) = 5(2)^3
\]
Now, calculate \( (2)^3 \):
\[
(2)^3 = 2 \times 2 \times 2 = 8
\]
Now substitute this back into the equation:
\[
f(3) = 5 \times 8 = 40
\]
Thus, the value of \( f(3) \) is \( \boxed{40} \).
