i use terry lee
i reckon its a real good textbook, but he tends to make huge jumps between lines, and do unneccesary manipulations just to show off
but the worked solutions were a life saver
haha my teacher marks 4 unit english stories
and she was telling us about how someone wrote theirs in all text message language
pretty inventive i thought, but he failed cause they didnt understand it
so they have 2^(-2/3) + 2^1/3
so they take a common factor of 2^(-2/3) out
and to get 2^1/3 into that form, you have to change it into 2 X 2(-2/3) because thats like 2/2^(2/3)
so then taking that common factor out
you get 2^(-2/3)X(1+2)
=3X2^(-2/3)
