解答

展开

(x^{\frac{1}{3}} - c^{\frac{1}{3}}) (x^{\frac{1}{3}} + c^{\frac{1}{3}})

x^{\frac{2}{3}} - c^{\frac{2}{3}}

求解步骤

(x^{\frac{1}{3}} - c^{\frac{1}{3}}) (x^{\frac{1}{3}} + c^{\frac{1}{3}})

Apply Difference of Two Squares

(x^{\frac{1}{3}} - c^{\frac{1}{3}}) (x^{\frac{1}{3}} + c^{\frac{1}{3}}) : x^{\frac{2}{3}} - c^{\frac{2}{3}}

= x^{\frac{2}{3}} - c^{\frac{2}{3}}

e x p an d \frac{1 - cos ( x ^{2} + y ^{2} )}{( x ^{2} + y ^{2} ) ^{2}}

e x p an d \frac{( x - 2 ) ^{2}}{9}

e x p an d \frac{( x y + ( 1 - δ ) n )}{n _{1} ( 1 + n _{1} )}

e x p an d (x + x^{2}) (3 x - 1)

e x p an d 3 x - 3 (x^{3} - 8)
