simplify sqrt(x-7)xsqrt(x+7)

simplify

x - 7 x x + 7

x (x - 7) (x + 7)

Solution steps

x - 7 x x + 7

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

x - 7 x + 7 = (x - 7) (x + 7)

= x (x - 7) (x + 7)

1 \cdot 1 0^{- 12} (e^{\frac{0.52}{0.026}} - 1)

2500 \cdot e^{0.025 - 0.02 5^{2}} \cdot e^{2 \cdot 0.02 5^{2}}

e^{- 125.33}

6.49 \cdot 1 0^{- 2}
