Simplify (a^2b^-2c^-1)/(e^7)

$\frac{a^{2} b^{- 2} c^{- 1}}{e^{7}}$

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

$\frac{a^{2} c^{- 1}}{e^{7} b^{2}}$

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

$\frac{a^{2}}{e^{7} b^{2} c}$
