Question

what is the negative square root of 169?

Explanation:

Step1: Recall square - root concept

The square root of a number \(x\) is a value \(y\) such that \(y^2=x\). For \(x = 169\), we know that \(13\times13=169\) and \((- 13)\times(-13)=169\).

Step2: Identify negative square - root

We want the negative square root. So the negative square root of 169 is \(-13\).

Answer:

\(-13\)
