if 1^2 = -1 then what does i^5+i^6+i^7= anyone give me somewhere to start on this one

I'm sure it was just a typo, but it should be . To compute just calculate what is, what is and what is, then add them together. For example, you know that , so . Continuing on, and continue in this process.
A simple but interesting result which we obtain from above is that : The sum of any 4 consecutive powers of is equal to zero. Hence using this result, Hence the value of the given expression is merely i.e. = and we know, Hence the required answer is
so how do we know that i^4 = 1 and why then would -i^8 = -1
since Square both sides, Now, square both sides again, so clearly
ok thanks again for your patience
