Step-by-step explanation:

{4}^{4} = {4}^{k - 2}

Since the BASES are the same, set the exponents equal

4 = k - 2

Move variables to the left-hand side and CHANGE its sign

- k + 4 = - 2

Move CONSTANT to the right-hand side and change its sign

- k = - 2 - 4

Calculate the difference

- k = - 6

Change the SIGNS on both sides of the equation

Solution :

k = 6
