If i = √-1 ,

then ...

i² = (√-1)² = -1

i³ = - √-1 = -i <== the answer to the question

i⁴ = (i²) · (i²) = (-1) · (-1) = 1

and then the whole thing starts over again, for higher powers of i .

A student scored a 72, 75, and 83 on the first three tests. All tests have a possibility of 100 points (no bonus points). Is it

alexira [117]

Add 72, 75, and 83, which equal 230. Then, since there are three values, you divide the total (230) by 3, which would equal 76.6 (cont), therefore meaning they can only raise their average (using the three tests, from a base grade of 0) to a 76.6 percent (or 77 if teacher rounds grade)
