Incorrect. 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\$ . To make your approximation, determine whether $\displaystyle\sqrt{{95}}\usepackage{cmbright}\Huge\$ is closer to $\displaystyle\sqrt{{{81}}}\usepackage{cmbright}\Huge\$ or $\displaystyle\sqrt{{{100}}}\usepackage{cmbright}\Huge\$ . Then use trial and error, squaring incrementally greater or lesser numbers, to find the best approximation of $\displaystyle\sqrt{{{95}}}\usepackage{cmbright}\Huge\$ . The correct answer is 9.7.
