a) √32 + √72 - √50 = √16*2+√36*2-√25*2 = 4√2 + 6√2 + 5√2 = 15√2
b) √12 + √243 - √108 = √4*3 + √81*3 - √36*3 = 2√3 + 9√3 - 6√3 = 5√3
c) √80 - √125 + √500 = √16*5 - √25*5 + √100*5 = 4√5 - 5√5 + 10√5 = 9√5
d) √6 + √24 + √486 = √6 + √4*6 + √81*6 = √6 + 2√6 + 9√6 = 12√6
e) √28 - √125 + √252 = √4*7 - √25*5 + √36*7 = 2√7 - 5√5 + 6√7 = 8√7 - 5√5
f) √44 + √99 + √1100 = √4*11 + √9*11 + √100*11 = 2√11 + 3√11 + 10√11 = 15√11
