Answer

$\frac{t^7}{u^{11}}$

Work Step by Step

We start with the given expression: $12^0t^7u^{-11}$ The zero as an exponent rule states that for every nonzero number $a$, $a^0=1$. Since $12^0=1$, and any number multiplied by $1$ is itself, we can remove this term from the expression: $t^7u^{-11}$. The negative exponent rule states that for every nonzero number $a$ and integer $n$, $a^{-n}=\frac{1}{a^n}$. We use this rule to rearrange the expression as follows: $\frac{t^7}{u^{11}}$
