simplify 2sqrt(x+1)*sqrt(x-1)

simplify

2 x + 1 \cdot x - 1

2 (x + 1) (x - 1)

Solution steps

2 x + 1 x - 1

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

x + 1 x - 1 = (x + 1) (x - 1)

= 2 (x + 1) (x - 1)

e^{- x} (1 + e^{x})

6.12 \cdot 1 0^{- 5}

2.535218256 \cdot 1 0^{- 6} (100)

3.69 \cdot 1 0^{- 2}

(\frac{L ^{3}}{2 π})^{- 2}
