Math Problem Statement

If f, of, x, equals, 6, start superscript, 4, x, end superscript, plus, 8f(x)=6 4x +8, what is the value of f, of, 1f(1), to the nearest hundredth (if necessary)?

Solution

To find the value of f(1)f(1) given the function f(x)=64x+8f(x) = 6^{4x} + 8, let's substitute x=1x = 1 into the equation.

Step 1: Substitute x=1x = 1 into the function

f(1)=64(1)+8f(1) = 6^{4(1)} + 8 f(1)=64+8f(1) = 6^{4} + 8

Step 2: Compute 646^4

64=6×6×6×6=12966^4 = 6 \times 6 \times 6 \times 6 = 1296

Step 3: Add 8

f(1)=1296+8=1304f(1) = 1296 + 8 = 1304

Thus, the value of f(1)f(1) is 1304.
