Question 1038301
#1:
Two binomials multiplied.  You already learned to do this but here, you do not have variables.  Just do what you already know.  Watch carefully, that the factors are both Complex.   {{{sqrt(-1)sqrt(-1)=-1}}}  and  {{{i^2=-1}}}.



#2:
Look for a pattern, unless you already know this pattern.

<pre>
Exponent         i raised to that exponent
1                         i
2                        -1
3                        -i
4                         1
5                         i
6                        -1
</pre>
Can you see what to do with this pattern?
