simplify sqrt(3+x)*sqrt(x^2-1)

simplify

3 + x \cdot x^{2} - 1

(x + 3) (x^{2} - 1)

Solution steps

3 + x x^{2} - 1

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

x + 3 x^{2} - 1 = (x + 3) (x^{2} - 1)

= (x + 3) (x^{2} - 1)

e^{- π \frac{0.04}{0.03}}

e^{(- 3 l n (x))}

1.6 \cdot 1 0^{- 199}

e^{- \frac{x}{0.06}}

(3 x + 1)^{2} (3 x - 1)^{2}
