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

simplify

4 + x \cdot 4 - x

(x + 4) (- x + 4)

Solution steps

4 + x 4 - x

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)

\frac{e ^{- 6 x}}{e ^{- 6 x}}

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

30 e^{- 0.019254 (12)}

(1)^{2} \cdot e^{- (1)}
