WebWe found one! This allows us to simplify the radical: \begin {aligned} \sqrt {75}&=\sqrt {\blueD {5^2}\cdot3} \\\\ &=\sqrt {\blueD {5^2}} \cdot \sqrt { {3}} \\\\ &=5\cdot \sqrt {3} \end {aligned} 75 = 52 ⋅ 3 = 52 ⋅ 3 = 5 ⋅ 3. So \sqrt {75}=5\sqrt {3} 75 = 5 3. WebWe write If we want to find the negative square root of a number, we place a negative in front of the radical sign.
