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

simplify

x - a \cdot x + a

(x - a) (x + a)

Solution steps

x - a x + a

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

x - a x + a = (x - a) (x + a)

= (x - a) (x + a)

\frac{156.9 6 ^{2}}{117.7 2 ^{2}}

6.8 \cdot 1 0^{- 4} \cdot 57

15 e^{- 0.15 (4.63)}

2.05 \cdot 60 0^{- 0.18}
