Question 297815
How do you solve -i to the 15th power?
--------------
There's nothing to be solved.  You can calculate {{{i^15}}}
i is the sqrt(-1)
{{{i^2 = -1}}}
{{{i^3 = -i}}}
{{{i^4 = 1}}}
{{{i^5 = i}}}
{{{i^6 = -1}}}
{{{i^7 = -i}}}
{{{i^8 = 1}}}
{{{i^9 = i}}}
It repeats every 4th power.
15 = 3*4 + 3 --> i^15 = i^3
= -i
