simplify sqrt(x-4)*sqrt(x+4)

simplify

x - 4 \cdot x + 4

(x - 4) (x + 4)

Solution steps

x - 4 x + 4

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

x - 4 x + 4 = (x - 4) (x + 4)

= (x - 4) (x + 4)

4.2 \times 1 0^{- 3}

- \frac{1}{2 ln ( 3 )} \cdot 3^{- 2^{2}}

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

(4 x^{2}) (3 x)
