Question

If a = √−√ √+√ and b = √+√ √−√ , find a + b + ab.

Answer 1

Answer:

1 2 √ 2 2 √ = √ 3 27 = 3 3 √ −64= −4 4 √ 16 = 2 4 √ −16 is not defined n 5 √ −1 ... In general, we find that n √ xn = x if n is odd, and n √ xn = |x| if n is even. ... then n √ ab = n √ a n √ b Radical of a product Product of radicals n if b = 0 ...
