Unformatted text preview: If c = 3, you could write out (a+b)^3 = (a+b) * (a+b) * (a+b) but then you can't simplify the * and the + mixture! In much the same way, sqrt can be thought of as an exponent (it's the 1/2 power), so sqrt(a*b) = sqrt(a) * sqrt(b) but sqrt(a+b) can't be rearranged in any nice way. 2. o The numerator and denominator of the following must be multiplied by √3 to rationalize 3/(3+√3). Explain why I think you are missing a part here…please complete and i`ll answer to this too...
