Chapter 5 - Section 5.1 - Exponents and Scientific Notation - Exercise Set: 66



Work Step by Step

We are given the expression $4^{0}+4x^{0}$. $4^{0}+4x^{0}=1+4(x^{0})=1+4\times1=5$ In general, $a^{0}=1$ when a is nonzero. In the second term, 4 and x are not in parentheses, so only x (the base of the exponent) is evaluated by the exponent.
