simplify cos(x)x^{-2}

Solution

simplify

cos (x) x^{- 2}

Solution

\frac{cos ( x )}{x ^{2}}

Solution steps

cos (x) x^{- 2}

Apply exponent rule:

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

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

= cos (x) \frac{1}{x ^{2}}

Apply the fraction rule:

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

= \frac{cos ( x ) \cdot 1}{x ^{2}}

Apply rule:

a \cdot 1 = a

cos (x) \cdot 1 = cos (x)

= \frac{cos ( x )}{x ^{2}}
