Simplify $\left(u^4\right)^3$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $4$ and $n$ equals $3$

Applicare la formula: $ab$$=ab$, dove $ab=4\cdot 3$, $a=4$ e $b=3$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=u^5$, $a^m=u^{12}$, $a=u$, $a^m/a^n=\frac{3u^{12}}{6u^5}$, $m=12$ e $n=5$

Applicare la formula: $\frac{ab}{c}$$=\frac{a}{c}b$, dove $ab=3u^{7}$, $a=3$, $b=u^{7}$, $c=6$ e $ab/c=\frac{3u^{7}}{6}$
