simplify sqrt(4-x)*sqrt(x^2-1)

simplify

4 - x \cdot x^{2} - 1

(- x + 4) (x^{2} - 1)

Solution steps

4 - x x^{2} - 1

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

- x + 4 x^{2} - 1 = (- x + 4) (x^{2} - 1)

= (- x + 4) (x^{2} - 1)

\frac{- 140}{20}

\frac{e ^{x}}{e ^{6 x}}

x^{4 n}

e^{wt}

e^{- y l n (c o s (x))}
