simplify f^{-1}[0.2]

Solution

simplify

f^{- 1} [0.2]

Solution

\frac{1}{5 f}

Solution steps

f^{- 1} (0.2)

Apply rule:

(a) = a

(0.2) = 0.2

= f^{- 1} \cdot 0.2

Apply exponent rule:

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

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

= \frac{1}{f} \cdot 0.2

Apply the fraction rule:

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

= \frac{1 \cdot 0.2}{f}

Multiply the numbers:

1 \cdot 0.2 = 0.2

= \frac{0.2}{f}

Simplify

\frac{0.2}{f} : \frac{2}{10 f}

= \frac{2}{10 f}

Cancel the numbers:

\frac{2}{10} = \frac{1}{5}

= \frac{1}{5 f}
