simplify (y^{-1}+y^{-2})(2y^{-3}-6y^{-4})

simplify

(y^{- 1} + y^{- 2}) (2 y^{- 3} - 6 y^{- 4})

(\frac{1}{y} + \frac{1}{y ^{2}}) (\frac{2}{y ^{3}} - \frac{6}{y ^{4}})

Solution steps

(y^{- 1} + y^{- 2}) (2 y^{- 3} - 6 y^{- 4})

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

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

= (\frac{1}{y} + \frac{1}{y ^{2}}) (2 y^{- 3} - 6 y^{- 4})

Simplify

2 y^{- 3} - 6 y^{- 4} : \frac{2}{y ^{3}} - \frac{6}{y ^{4}}

= (\frac{1}{y} + \frac{1}{y ^{2}}) (\frac{2}{y ^{3}} - \frac{6}{y ^{4}})

x \to \infty lim (\frac{1}{x \cdot lo g _{e} ( x )})

x \to 2 - lim (\frac{x - 2}{x - 2})

x \to \infty lim (1 + \frac{a}{x})

\int \frac{3}{( 5 v - 1 ) ^{4}} d v

\frac{d}{d x} (cos (x) - x)
