Change this radical to an algebraic expression with fractional exponents. √y^2 The exponent on y is:
Wewaii [24]
The power rule (or law of indices) related to root is given
x^{ \frac{1}{2} }=  \sqrt[2]{x}

We have \sqrt{ y^{2} }
Rewrite according to the rule we have y^{ \frac{2}{2} } = y^{1}

The exponent on y is '1'
