simplify sqrt(x+9)*sqrt(x-9)

simplify

x + 9 \cdot x - 9

(x + 9) (x - 9)

Solution steps

x + 9 x - 9

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

x + 9 x - 9 = (x + 9) (x - 9)

= (x + 9) (x - 9)

8 c^{3} (x - c)^{3}

3000 (1 + 0.0298)^{- 6}

e^{- 18 \cdot \frac{0.332}{12}}

e^{- 3} \cdot e^{3}

e^{4} \cdot e^{3}
