simplify φ^{-1}(0.9)

Solution

simplify

φ^{- 1} (0.9)

Solution

\frac{9}{10 φ}

Solution steps

φ^{- 1} (0.9)

Apply rule:

(a) = a

(0.9) = 0.9

= φ^{- 1} \cdot 0.9

Apply exponent rule:

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

φ^{- 1} = \frac{1}{φ}

= \frac{1}{φ} \cdot 0.9

Apply the fraction rule:

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

= \frac{1 \cdot 0.9}{φ}

Multiply the numbers:

1 \cdot 0.9 = 0.9

= \frac{0.9}{φ}

Simplify

\frac{0.9}{φ} : \frac{9}{10 φ}

= \frac{9}{10 φ}
