化简 sqrt((16x^{12))/(x^4)}-3x^6(x^{-1})^2

解答

化简

\frac{16 x ^{12}}{x ^{4}} - 3 x^{6} (x^{- 1})^{2}

x^{4}

求解步骤

\frac{16 x ^{12}}{x ^{4}} - 3 x^{6} (x^{- 1})^{2}

\frac{16 x ^{12}}{x ^{4}} = 4 x^{4}

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

= 4 x^{4} - 3 x^{6} \frac{1}{x ^{2}}

化简

3 x^{6} \frac{1}{x ^{2}} : 3 x^{4}

= 4 x^{4} - 3 x^{4}

s im pl i f y - 11 ab - 15 ab + 26 ab

s im pl i f y 23 + 43

s im pl i f y (2 i + 5) + (4 i - 7)

s im pl i f y \frac{3 x ^{2}}{x ^{2} - x - 30} - \frac{3 x + 5}{x - 6}
