simplify sqrt(a-1)*sqrt(a+1)

simplify

a - 1 \cdot a + 1

(a - 1) (a + 1)

Solution steps

a - 1 a + 1

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

a - 1 a + 1 = (a - 1) (a + 1)

= (a - 1) (a + 1)

1.45 \cdot 1 0^{- 4}

(x)^{\frac{1}{3}}

450 \cdot e^{- 1.128}

e^{((- 0.5))}
