simplify sqrt(9-x^2)*sqrt(x^2-4)

simplify

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

(- x^{2} + 9) (x^{2} - 4)

Solution steps

9 - x^{2} x^{2} - 4

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

- x^{2} + 9 x^{2} - 4 = (- x^{2} + 9) (x^{2} - 4)

= (- x^{2} + 9) (x^{2} - 4)

(z^{4} - 3 z^{3} + 2 z^{2} - 4 z + 4) (z - 1)^{- 1}

j^{2} (j + 1)^{2}

(x + 1)^{- 1}

(0.045 x^{750}) x^{4}

(6.67 \cdot 1 0^{- 11}) (58.8) (5.97 \cdot 1 0^{24})
