Need help with math functions.

Is it just me or does the math.sqrt(x) function not work??? I keep trying both in sqrt(x) and math.sqrt(x) and neither work in my program. I’ve used the help(‘math.sqrt’) function and it TELLS me to use sqrt(x) and it STILL doesn’t work. Please help. If I had to guess I don’t have a math library but I have no idea where to look for it.

@AceNinjaFire do you import math?
import math print(math.sqrt(4))
