化简 ((x^3)(x^4))/(x^{15)}

解答

化简

\frac{( x ^{3} ) ( x ^{4} )}{x ^{15}}

\frac{1}{x ^{8}}

求解步骤

\frac{( x ^{3} ) ( x ^{4} )}{x ^{15}}

化简

(x^{3}) (x^{4}) : x^{3} x^{4}

= \frac{x ^{3} x ^{4}}{x ^{15}}

化简

\frac{x ^{3}}{x ^{15}} : \frac{1}{x ^{12}}

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

化简

\frac{x ^{4}}{x ^{12}} : \frac{1}{x ^{8}}

= \frac{1}{x ^{8}}
