6. Compute the modulus and argument of each complex number. I did a-c and f.
D. -5
E. -5+5i
G. -3-4i

7. Let z= -5sqrt3/2+5/2i and w= 1+sqrt3i
a. convert z and w to polar form
b. calculate zw using De Moivres Theorem
c. calculate (z/w) using De M's theorem

Please help with these two problems? I did 1-6 and 9-10 already.
