Answer 2

Square root of 169 is either 13 or -13.

When we prime factorize 169, we get,

$\begin{tabular}{c|l}13&169\\ \cline{2-}&13\\ \cline{2-}\end{tabular}$

Thus we get 169 = 13².

And according to negative × negative = positive, the square root of 169 can be -13 too, and the prime factorization can also be written as follows:

$\begin{tabular}{c|l}-13&169\\ \cline{2-}&-13\\ \cline{2-}\end{tabular}$

169 = (-13)².

Thus we can say that,

√169 = ± 13
