simplify sqrt(25-x^2)sqrt(x^2-16)

simplify

25 - x^{2} x^{2} - 16

(- x^{2} + 25) (x^{2} - 16)

Solution steps

25 - x^{2} x^{2} - 16

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

- x^{2} + 25 x^{2} - 16 = (- x^{2} + 25) (x^{2} - 16)

= (- x^{2} + 25) (x^{2} - 16)

(3 a^{6} b^{2} c) (2 a^{3} b c)

198.5 \cdot 1 0^{- 12}

\frac{4}{3} π (1 0^{4})^{3}

e^{- (x - 1 + l n ∣ x - 1 ∣)}

3 \cdot 2 5^{- 0.5}
