Basic Math Examples

$\frac{9^{- 1} z^{- 1}}{y}$

Step 1

Move $9^{- 1}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{z^{- 1}}{y \cdot 9}$

Step 2

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

$\frac{1}{y \cdot 9 z}$

Step 3

Move $9$ to the left of $y$ .

$\frac{1}{9 y z}$
