i) we just foiled

and since

Should there be parenthesis for the fraction in ii)? otherwise just combine the i terms

iii)

so we now have

In general, to evaluate divide n by 4, and take the remainder as the power, for instance remainder 3, so

this is why we divide by 4, the cycle repeats as you see here - Aug 25th 2009, 08:40 PMrel85

group the i terms as you would x terms - Aug 25th 2009, 08:46 PMartvandalay11

so square both sides
