simplify x^{-2}y

Solution

simplify

x^{- 2} y

\frac{y}{x ^{2}}

Solution steps

x^{- 2} y

Apply exponent rule:

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

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

= \frac{1}{x ^{2}} y

Apply the fraction rule:

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

= \frac{1 \cdot y}{x ^{2}}

Apply rule:

1 \cdot a = a

1 \cdot y = y

= \frac{y}{x ^{2}}

(- x^{4} + 6) - (x^{4} - 6)

(- 7 m n^{6}) (- 3 mn) (- 5 m^{6} n^{3})

4 x^{2} - 81 y^{6}

9 (7 h - 4 k) + 10 k - 5 (6 k - 7 h)

2 - 72 + 3 - 32
