This is the question I have and I have no idea how to write the code!
Convert the complex number 8-7j into exponential and polar form. [2 marks]
I know already
syms a a=8-7j [theta, r]cart2pol(8, 7)
for the polar for but thats it
Find all five values of the following expression, giving your answers in Cartesian form: (-2+5j)^(1/5) [6 marks]
Any ideas?

My lecturer told us to teach our selves how to use it, and complete the assignment! Thanks for the help, it had me stumped!
