化简 (x-y)^2(x-w)^2

解答

化简

(x - y)^{2} (x - w)^{2}

(x - y)^{2} (x - w)^{2}

求解步骤

(x - y)^{2} (x - w)^{2}

使用指数法则:

a^{m} b^{m} = (ab)^{m},

假定

a \geq 0, b \geq 0

(x - y)^{2} (x - w)^{2} = ((x - y) (x - w))^{2}

= ((x - y) (x - w))^{2}

使用指数法则:

(a \cdot b)^{n} = a^{n} b^{n}

= (x - y)^{2} (x - w)^{2}

s im pl i f y 2 x 3 x^{2}

s im pl i f y 4 b^{3} b

s im pl i f y (e^{x^{2}}) (e^{l n (x)})

s im pl i f y 3 x^{- 0.5}
