simplify (sqrt(x)-sqrt(y))(sqrt(x)-sqrt(y))

simplify

(x - y) (x - y)

x - 2 x y + y

Solution steps

(x - y) (x - y)

Apply exponent rule:

aa = a^{2}

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

= (x - y)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

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

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

(x)^{2} = x

(y)^{2} = y

= x - 2 x y + y

[(- 5)^{1}]^{3}

2 π \cdot 4000 \cdot 4.329 \cdot 1 0^{- 3}

e^{- 0.99}

\frac{e ^{- (x + y)}}{e ^{- x}}

\frac{x + 2}{x - 1}
