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

f is the midpoint of

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
