we can write the above question in this form
(i^2)^296 + (i^2)^295 + (i^2)^294 + (i^2)^293 +(i^2)^292 + (i^2)^291 + (i^2)^290 + (i^2)^289 + (i^2)^288 + (i^2)^287=
we know that i^2 is -1
subsitute it in the above information..
now if the power is odd then it(i.e., -1) will remain as -1.... because (-1)^3 is -1×-1×-1= -1 right! ..if the power is even it will become 1.... eg..(-1)^2= -1×-1=1 right!.
but for huge numbers, to check whether the power is even or odd..we can simply divide it with 2..if the number is divisible by 2 then it is even number if not then it is odd number...eg..296 is divisible be by 2 ..2×148 so even number....in the same way for all numbers...we get
1 + (-1) + 1 + (-1) + 1 + (-1) + 1 + (-1) + 1 + (-1) =0 ..is the answer
(i^2)^296 + (i^2)^295 + (i^2)^294 + (i^2)^293 +(i^2)^292 + (i^2)^291 + (i^2)^290 + (i^2)^289 + (i^2)^288 + (i^2)^287=
