Simplify $\sqrt{b^n}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $n$ and $n$ equals $\frac{1}{2}$

Simplify $\sqrt[4]{b^n}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $n$ and $n$ equals $\frac{1}{4}$

Wenden Sie die Formel an: $x^mx^n$$=x^{\left(m+n\right)}$, wobei $x=b$, $m=\frac{1}{2}n$ und $n=\frac{1}{4}n$
