You asked:

Evaluate the expression: \(\sqrt{{7}^{2} - {5}^{2} - 15}\)

MathBot Answer:

\[\sqrt{{7}^{2} - {5}^{2} - 15} = 3\]

\[\begin{aligned}\sqrt{{7}^{2} - {5}^{2} - 15}& = \sqrt{7^{2} - 5^{2} - 15}\\& = \sqrt{49 - 5^{2} - 15}\\& = \sqrt{49 - 25 - 15}\\& = \sqrt{24 - 15}\\& = \sqrt{9}\\& = 3\end{aligned}\]
