Question 1128736: Evaluate the exponential function for the indicated value of x.
g(x) = 1/3 (4)^(x − 4) for x = 8.
I substituted the given variable for x and my answer keeps being incorrect. My first answer was 65524/3, but then I converted it to a decimal which the answers were 21841 and 21841.3. Can someone explain my mistake in solving the equation?

In general, we can't help you explain your mistake without seeing exactly what calculations you did.

However, in this case, I can see what you did wrong. You simply did not evaluate the given expression.

The correct evaluation would be



You calculated
