Can you help me with these exercises 1. z1=cos*pi/8+i*sin*pi/8;
z2=1+i √3
(z1*z2)^8=?
2.Solve in C ecuation z^4+81=0
3.Solve ecuation x^3-4x^2+x+6=0

Which two transformations are applied to pentagon abcde to create a'b'c'd'e'? (4 points) translated according to the rule (x, y) ? (x + 8, y + 2) and reflected across the x-axis translated according to the rule (x, y) ? (x + 2, y + 8) and reflected across the y-axis translated according to the rule (x, y) ? (x + 8, y + 2) and reflected across the y-axis translated according to the rule (x, y) ? (x + 2, y + 8) and reflected across the x-axis
