Answer 1

Given:

`√(225)`
`\begin{gathered} Factor\text{ the number;} \\ √(225)=\pm√(15*15)=\pm√(15^2) \\ \\ Applying\text{ the radical rule;} \\ √(a^2)=a,\text{ when }a\ge0 \\ Then, \\ √(15^2)=\pm15 \\ \\ Hence, \\ √(225)=\pm15=15\text{ OR }-15 \end{gathered}`

Therefore, the square root of 225 is 15 or -15
