simplify 9x^0y^{-3}

Solution

simplify

9 x^{0} y^{- 3}

Solution

\frac{9}{y ^{3}}

Solution steps

9 x^{0} y^{- 3}

Apply exponent rule:

a^{0} = 1,

assuming

a \neq = 0

x^{0} = 1

= 9 \cdot 1 \cdot y^{- 3}

Apply exponent rule:

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

y^{- 3} = \frac{1}{y ^{3}}

= 9 \cdot 1 \cdot \frac{1}{y ^{3}}

Multiply the numbers:

9 \cdot 1 = 9

= 9 \cdot \frac{1}{y ^{3}}

Apply the fraction rule:

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

= \frac{9 \cdot 1}{y ^{3}}

Multiply the numbers:

9 \cdot 1 = 9

= \frac{9}{y ^{3}}
