expand (xy^2)*2y^{-1}

expand

(x y^{2}) \cdot 2 y^{- 1}

2 x y

Solution steps

(x y^{2}) \cdot 2 y^{- 1}

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 2 = 2

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

Cancel the common factor:

y

= 2 x y

\frac{c ( x ^{2} - 7 )}{p}

\frac{1}{4} k e^{- 4 x}

\frac{e ^{1 - x}}{e ^{1 + x}}
