N= P-180. so the computer would originally be 720 dollars. reduced by 25%, or 180, the new price is 540.
43 47 53 59 are the prime numbers
Are you sure you've copied down the original problem exactly as given? i38 = 38i can't be simplified. Perhaps you meant i^38, which is a different matter.
Note that i^38 = i^32 * I^4 * I^2.
Note that i^0, i^4, i^8, etc., all equal 1. Therefore,
i^38 = (1)(1)i^2 = 1*(-1) = -1 (answer)
3345 because it’s squared
