Could someone help me on this? I think this is Alegbra 2 level math.

The powers of i repeat in blocks of four:

i,i2,i3,i4=1,−1,−i,i

Therefore, the sum telescopes:

$\begin{align*} i + 2i^2 + 3i^3 + 4i^4 + \dots + 64i^{64} &= i + 2(-1) + 3(-i) + 4i + \dots + 64i \\ &= (i - 2i + 3i - 4i + \dots + 64i) + (2 - 3 + 4 - \dots + 64) \\ &= 0 + (2 + 64) \cdot 32 \\ &= \boxed{496}. \end{align*}$

i + [2i^2 + 3i^3 + 4i^4 + 5i^5 +..............+64i^64] ==32  -  32i

As of what the first guest, i has four different stages. These stages are i, -1, -i, 1.Through these stages, we can see that i + 2i² + 3i³ + 4i⁴ is equal to 2 - 2i. As we continue to 8i⁸, the answer is 4 - 4i. We can see a pattern, which is that for each four stages, we get 2 - 2i, no matter what. 64 / 4 is 16, so therefore the answer is 16 * (2 - 2i), or 32 - 32i.

Your username is so correct LOL
