simplify sqrt(5-x)sqrt(x^2-9)

simplify

5 - x x^{2} - 9

(- x + 5) (x^{2} - 9)

Solution steps

5 - x x^{2} - 9

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

- x + 5 x^{2} - 9 = (- x + 5) (x^{2} - 9)

= (- x + 5) (x^{2} - 9)

(4 x - 6 y^{2})^{2} (4 x + 6 y^{2})^{2}

5 (1.3)^{- (7)}

2.1 \cdot 1 0^{- 5}
