You asked:
Evaluate the expression: \(\sqrt{{6}^{2} - {4}^{2}}\)
MathBot Answer:
\[\sqrt{{6}^{2} - {4}^{2}} = 2 \sqrt{5} \approx 4.47213595499957939281834733746255\]
\[\begin{aligned}\sqrt{{6}^{2} - {4}^{2}}& = \sqrt{6^{2} - 4^{2}}\\& = \sqrt{36 - 4^{2}}\\& = \sqrt{36 - 16}\\& = \sqrt{20}\\& = 2 \cdot \sqrt{5}\end{aligned}\]
