Ok guys, here's another easy one that's got me foxed!
given that
deduce
earlier I was asked to use the series to find which is OK because it fits the (1 + x) pattern - but sqrt 12 ?
I thought of sqrt 12 = sqrt (10 x 1.2) = sqrt 10. sqrt (1 + 0.2) but this means I have to know what sqrt 10 is and if I knew that, I wouldn't have a problem with sqrt 12!
sqrt 12 = 2 sqrt 3 but this doesn't get me anywhere either. Can anyone see something I can't?
regards
