Math Problem Statement

Given f(n) = 3(2^n)^3, f(5) = ?

Solution

The problem requires us to evaluate the function f(n)=3(2n)3f(n) = 3(2^n)^3 at n=5n = 5.

Let's rewrite the function to make it simpler to understand:

f(n)=3(2n)3f(n) = 3(2^n)^3

This can be further simplified to:

f(n)=3(2n)3=323nf(n) = 3 \cdot (2^n)^3 = 3 \cdot 2^{3n}

Now, substitute n=5n = 5:

f(5)=323×5=3215f(5) = 3 \cdot 2^{3 \times 5} = 3 \cdot 2^{15}

Calculating 2152^{15}:

215=327682^{15} = 32768

Thus,

f(5)=332768=98304f(5) = 3 \cdot 32768 = 98304

So, the value of f(5)f(5) is 98,304.
