Evaluate \(i+2i^2+3i^3+4i^4+...+64i^64.\)

 

The 'i' is √-1 (imaginary number)

Okay so if you have a graphing calculator (Ti-84 Plus maybe) there is a way to figure out i on your calculator. You press the blue button that says 2ND then press the decimal button and you get the i for imaginary numbers. But anywho,

 

i+2i^2+3 can be simplfied down to...

i+(-2)+3

=i+1
