Ok got it. If you have any questions just ask in the chat below :)
I= sqrt (-1)
If the power is
- even then the value could be -1 or 1
-odd then the value could be -i or i
99 is odd so now is
-i if (99+1)/2 is even or is
i is (99+1)/2 is odd
Now check (99+1)/2= 100/2= 50,
50 is even so
i^99 = -i
4 x 1 thousand (1000) = 4000
21 x 1 ten (10) = 210
4000
+ 210
---------
4210
=4210 (four thousand-two hundred and ten
