simplify sqrt(x+2)*sqrt(x-2)

simplify

x + 2 \cdot x - 2

(x + 2) (x - 2)

Solution steps

x + 2 x - 2

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

x + 2 x - 2 = (x + 2) (x - 2)

= (x + 2) (x - 2)

\frac{d}{d t} (e^{- s t})

(2 m^{3}) (4 m^{2})

e^{- z}

7.4 \cdot 1 0^{- 6}
