simplify (2ef^{-1})/(e^{-1)}

simplify

\frac{2 e f ^{- 1}}{e ^{- 1}}

\frac{2 e ^{2}}{f}

Solution steps

\frac{2 e f ^{- 1}}{e ^{- 1}}

Cancel the common factor:

e^{- 1}

= 2 e^{2} f^{- 1}

Apply exponent rule:

a^{- 1} = \frac{1}{a}

f^{- 1} = \frac{1}{f}

= 2 e^{2} \frac{1}{f}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot 2 e ^{2}}{f}

Multiply the numbers:

1 \cdot 2 = 2

= \frac{2 e ^{2}}{f}

\frac{1}{30} + \frac{1}{20}

7 + (- 12)

180 \div 30

\frac{x ^{5}}{x ^{- 3}}

- 15 k - 1 + 12 + 2 k
