You asked:

Evaluate the expression: \({81}^{\frac{1}{2}} - {\left( -3 \right)}^{2} + {5}^{0}\)

MathBot Answer:

\[{81}^{\frac{1}{2}} - {\left( -3 \right)}^{2} + {5}^{0} = 1\]


\[\begin{aligned}{81}^{\frac{1}{2}} - {\left( -3 \right)}^{2} + {5}^{0}& = \sqrt{81} - \left(-3\right)^{2} + 5^{0}\\& = 9 - \left(-3\right)^{2} + 5^{0}\\& = 9 - 9 + 5^{0}\\& = 9 - 9 + 1\\& = 0 + 1\\& = 1\end{aligned}\]
