Answer 2

Answer:

The simplified form of the given expression is 13.

Step-by-step explanation:

The given expression is

$\sqrt{169}$

It can be written as

$\sqrt{13\times 13}$

$\sqrt{13^2}$

$(13^2)^{\frac{1}{2}}$                $[\because \sqrt{x}=x^{\frac{1}{2}}]$      

$13^{\frac{2}{2}}$                   $[\because (x^m)^n=x^{mn}]$      

$13^{1}$

$13$

Therefore the simplified form of the given expression is 13.
