To find $f\left(\frac{5}{2}\right)$, we substitute $x = \frac{5}{2}$ into the function $f(x) = 4^x$, which gives us $4^{\frac{5}{2}}$. This simplifies to $2^5 = 32$, since $4 = 2^2$ and thus $4^{\frac{5}{2}} = (2^2)^{\frac{5}{2}} = 2^5$.

Find the Function Value Let f(x)=4x. Find (52). \text { Let } f ( x ) = 4 ^ { x } \text {. Find } \left( \frac { 5 } { 2 } \right) \text {. } Let f(x)=4x. Find (25​).
