Math Question

Quick math question

if someone could show me how to do it, I would be eternally in your debt
(note that everything except "x" are exponents)


(x^a+b)^a-b
_________

(x^a-2b)^a+2b

Sorry I didn't take alien languages back in school... I shall however hazard a guess at the answer being either 42, magnets, or it's a trap.

(x^(a + b))^(a - b)/(x^(a - 2b))^(a + 2b)



x^((a + b) * (a - b) - (a - 2b) * (a + 2b))
(a + b)(a - b) by (a - 2b)(a + 2b)]
= x^(a² - b² - (a² - 4b²))
= x^(a² - b² - a² + 4b²)
= x^(3b²)

oh, I see what you did.

Thanks
