How many real numbers are not in the domain of the function

f(x) = 1/(x - 64) + 1/(x^2 - 64) + 1/(x^3 - 64) + 1/(x^4 - 64)

#1**0 **

This happens when $x = 64, x^2 = 64, x^3 = 64, x^4 = 64$ because then the denominator will be $0.$

Thus the answer is $4.$

If you are looking for the values, they are $64, 8, 4, 2.$
