Incorrect. Remember that $\displaystyle\sqrt{{700}}\cdot\sqrt{{525}}=\sqrt{{{700}\cdot{525}}}\usepackage{cmbright}\Huge\$ . Factor $\displaystyle{700}\cdot{525}\usepackage{cmbright}\Huge\$ in terms of products of square numbers, if possible. Then simplify the result and be sure that M is not a multiple of a square.
