Question

plz tell how to solve this equation.​

Answer 1

$\frac{ \sqrt{125} {y}^{2} }{5 {y}^{2} } = \frac{ \sqrt{125} }{5}$

$\frac{ \sqrt{125} }{5} = \frac{ \sqrt{25 \times 5} }{ \sqrt{5 \times 5} } = \frac{ \sqrt{25} \times \sqrt{5} }{ \sqrt{5} \times \sqrt{5} } = \frac{5}{ \sqrt{5} }$

$\frac{5}{ \sqrt{5} } = \frac{ \sqrt{5} \times \sqrt{5} }{ \sqrt{5} } = \sqrt{5}$
