Multiply the following √( - 15) * √( - 15)

Question

Multiply the following
`√( - 15) * √( - 15)`

Answer 1

Answer: -15

Given:

`\sqrt[]{-15}*\sqrt[]{-15}`

Since the radical rule states that:

`\begin{gathered} \sqrt[]{a}\sqrt[]{a}=a \\ \Rightarrow\sqrt[]{-15}*\sqrt[]{-15}=-15 \end{gathered}`

Therefore, the answer is -15.
