Solution steps

\frac{81}{225}

Apply radical rule:

a = a^{\frac{1}{2}}

= ((\frac{81}{225})^{\frac{1}{2}})^{\frac{1}{2}}

Apply exponent rule:

(a^{b})^{c} = a^{b c}

= (\frac{81}{225})^{\frac{1}{2} \cdot \frac{1}{2}}

\frac{1}{2} \cdot \frac{1}{2} = \frac{1}{4}

= (\frac{81}{225})^{\frac{1}{4}}

\frac{81}{225} = \frac{9}{25}
