I need to prove that if T is regular matix than: ((T^-1)AT)^n=(T^-1)(A^n)T

You are right thanks

You are right thanks

I tried it in the trigonometric way : 2r^9[isin(9*theta)]=9|z|^4 but where should I go from here ?

Im trying to solve this equation for along time I tries to use the formulas for power 3 but it ddint help I think it shuld be factoring the left side but I couldnt make it z^9-z'^9=9|z|^4 please help

Its clear for me now, thanks

well, the prime is not mention in my question but after what u said I agree that its must be. still I dont know where to start proving that and how can I use Euclid's Algorithm for the solution

I need to prove that if a,b, a is not 0, in Zp than there is n that b = na how should I start proving that ?
