$\frac{5^{- 2} t^{4} u^{- 3}}{t^{- 7} u^{6}}$

Step 1

Move $5^{- 2}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{t^{4} u^{- 3}}{t^{- 7} u^{6} \cdot 5^{2}}$

Step 2

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

$\frac{t^{4}}{t^{- 7} u^{6} \cdot 5^{2} u^{3}}$

Step 3

Multiply $u^{6}$ by $u^{3}$ by adding the exponents.
