Question

Simplify:

`(i^592 + i^590 + i^588 + i^586 + i^584)/(i^582 + i^580 + i^578 + i^576 + i^574)`

Sum

Solution

`(i^592 + i^590 + i^588 + i^586 + i^584)/(i^582 + i^580 + i^578 + i^576 + i^574)`

= `(i^584 (i^8 + i^6 + i^4 + i^2 + 1))/(i^574 (i^8 + i^6 + i^4 + i^2 + 1))`

= `(i^584)/(i^574)`

= i10

= (i2)5

= (–1)5

= – 1
