simplify 3x^2(x^4+2x^{-3})

Solution

simplify

3 x^{2} (x^{4} + 2 x^{- 3})

Solution

3 x^{2} (x^{4} + \frac{2}{x ^{3}})

Solution steps

3 x^{2} (x^{4} + 2 x^{- 3})

Apply exponent rule:

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

x^{- 3} = \frac{1}{x ^{3}}

= 3 x^{2} (x^{4} + 2 \cdot \frac{1}{x ^{3}})

Simplify

2 \cdot \frac{1}{x ^{3}} : \frac{2}{x ^{3}}

= 3 x^{2} (x^{4} + \frac{2}{x ^{3}})
