7 sqrt 20 = 7 sqrt(4*5) = 14 sqrt 5
so
14/12 = 7/6
same sort of deal for the second one
sqrt (4*2) = 2 sqrt 2
sqrt(24) = sqrt(6*4) =2 sqrt(2)sqrt(3)
1/sqrt 3 = sqrt(3) /3
so
14/12 = 7/6
same sort of deal for the second one
sqrt (4*2) = 2 sqrt 2
sqrt(24) = sqrt(6*4) =2 sqrt(2)sqrt(3)
1/sqrt 3 = sqrt(3) /3
