simplify z^{-1}*z^{-1}

Solution

simplify

z^{- 1} \cdot z^{- 1}

Solution

\frac{1}{z ^{2}}

Solution steps

z^{- 1} z^{- 1}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

z^{- 1} z^{- 1} = z^{- 1 - 1}

= z^{- 1 - 1}

Subtract the numbers:

- 1 - 1 = - 2

= z^{- 2}

Apply exponent rule:

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

z^{- 2} = \frac{1}{z ^{2}}

= \frac{1}{z ^{2}}
