Question

What is the base of the exponent in the function when the function is written using only rational numbers and is in simplest form?

Answer 1

The general formula for an exponential function is 
$f(x)=b^x$

In this case, b is the base which is any real number greater than 0 and is not 1. Additionally, the domain of an exponential function is all real numbers due to the fact that the exponential function is defined by real numbers. While the range is all real numbers greater than zero. 

Answer 2

If the exponent is f(x)3[^3square root *]^2x then the answer is 4.
