Step 1.1

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

${(\frac{1}{t^{- 7 - 1}})}^{\frac{5}{16}}$

Step 1.2

Subtract $1$ from $- 7$ .

${(\frac{1}{t^{- 8}})}^{\frac{5}{16}}$

Step 2

Move $t^{- 8}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

${(t^{8})}^{\frac{5}{16}}$

Step 3
