${(\frac{5 t^{- 3}}{t^{2}})}^{- 2} \cdot \frac{2}{t^{- 2}}$

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

${(\frac{5 t^{- 3}}{t^{2}})}^{- 2} \cdot \frac{2}{\frac{1}{t^{2}}}$

Step 2

Move $t^{- 3}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

${(\frac{5}{t^{2} t^{3}})}^{- 2} \cdot \frac{2}{\frac{1}{t^{2}}}$

Step 3

Multiply $t^{2}$ by $t^{3}$ by adding the exponents.
