expand (y^{-1})^4

Solution

expand

(y^{- 1})^{4}

Solution

\frac{1}{y ^{4}}

Solution steps

(y^{- 1})^{4}

Apply exponent rule:

(a^{b})^{c} = a^{b c}

= y^{(- 1) \cdot 4}

(- 1) \cdot 4 = - 4

= y^{- 4}

Apply exponent rule:

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

= \frac{1}{y ^{4}}

- \frac{( 6 x - 5 )}{( 3 x ^{2} - 5 x + 7 ) ^{2}}

(\partial)/(\partial x)((y)(x-y))

\frac{\partial}{\partial x} ((y) (x - y))

((e^{-s}))/(s(s^2+1))

\frac{( e ^{- s} )}{s ( s ^{2} + 1 )}

simplify (-1+sqrt(2)i)^4 simplify

(- 1 + 2 i)^{4}

expand ((3-x)(x^2+2))/((x-5)(x+3))expand

\frac{( 3 - x ) ( x ^{2} + 2 )}{( x - 5 ) ( x + 3 )}
