If k^n=nk^n-1 is true. Then can 2 = 1? As 2 = 2^1 = 1*2^0 = 1 * 1 = 1?

Your first statement is false. $k^n \ne nk^{n-1}$

I am not sure what contradiction you are trying to prove or disprove, but $2^1 \neq 1 * 2^0$

If k^n=nk^n-1 is true. Then can 2 = 1? As 2 = 2^1 = 1*2^0 = 1 * 1 = 1?

kⁿ = nk^n–1 is not true.

kⁿ = kk^n–1 is true.
