SOLUTION: what is: i squared i cubed and i to the fourth power?
You can put this solution on YOUR website! i take it you mean i is "the square root of minus 1"? If so, if i = then square both sides gives = -1.

SOLUTION: In an arithmetic sequence the 8th term is twice the 4th …
In an arithmetic sequence the 8th term is twice the 4th term and the 20th term is 40. Find the common difference and the sum of the terms from 8th to the 20th inclusive.. a= first term n= number of terms d = common difference 8th. Term T8 = a+7d T4 = a+3d T8=2*T4 a+7d=2(a+3d) a+7d=2a+6d a-d=0 a=d T20 = a+19d -Therefore T4 = 4a T8=8a T20=20a 40 ...
form the first three consecutive terms of a G.P. - Algebra …
Since the sum of the 3rd and 5th terms of the AP is 20, the 4th term is 10. If the common difference in the AP is d, then the 2nd term is 10-2d and the 8th term is 10+4d. Since the 2nd, 4th, and 8th terms of the AP form a GP, or Both values of d satisfy the conditions of the problem; but the AP with d=0 is not very interesting.

Raise to the 4th power to get Square to get So we can see that which means that the function is an even function. Graphically, this function has symmetry across the y-axis. Here's a tip: with polynomials, if all of the exponents are even, then the function is even. On the flip side, if all of the exponents are odd, then the function is odd.
