simplify 5-20x^{-2}

Solution

simplify

5 - 20 x^{- 2}

Solution

5 - \frac{20}{x ^{2}}

Solution steps

5 - 20 x^{- 2}

Apply exponent rule:

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

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

= 5 - 20 \cdot \frac{1}{x ^{2}}

Simplify

20 \cdot \frac{1}{x ^{2}} : \frac{20}{x ^{2}}

= 5 - \frac{20}{x ^{2}}
