Question

solve for r.
10^r = 1
r = \square

Explanation:

Step1: Recall the property of exponents

Any non - zero number raised to the power of 0 is 1. In the equation \(10^{r}=1\), we know that for the base 10 (which is non - zero), when the exponent \(r\) makes \(10^{r}=1\), by the property \(a^{0} = 1\) (where \(a
eq0\)), here \(a = 10\). So we can conclude that \(r = 0\) because \(10^{0}=1\).

Answer:

\(0\)
