Correct. 95 is between the perfect squares 81 and 100. So $\displaystyle\sqrt{{{95}}}\usepackage{cmbright}\Huge\$ must be between $\displaystyle\sqrt{{{81}}}\usepackage{cmbright}\Huge\$ and $\displaystyle\sqrt{{{100}}}\usepackage{cmbright}\Huge\$ .

$\displaystyle\sqrt{{{81}}}={9}\usepackage{cmbright}\Huge\$ and $\displaystyle\sqrt{{{100}}}={10}\usepackage{cmbright}\Huge\$

Because 95 is closer to 100 than it is to 81, $\displaystyle\sqrt{{{95}}}\usepackage{cmbright}\Huge\$ is probably about 9.7 or 9.8.

$\displaystyle{9.7}\cdot{9.7}={94.09}\usepackage{cmbright}\Huge\$ and $\displaystyle{9.8}\cdot{9.8}={96.04}\usepackage{cmbright}\Huge\$

$\displaystyle{{\left({9.7}\right)}}^{{2}}\usepackage{cmbright}\Huge\$ gives a closer approximation than $\displaystyle{{\left({9.8}\right)}}^{{2}}\usepackage{cmbright}\Huge\$ , so the answer is 9.7.
