pow is built into the language(not part of the math library). The problem is that you haven't imported math.
Try this:
import math
math.sqrt(4)

January 21, 2023[Python] The difference between "import math" and "from math import *"
The first method imports using the math namespace. You would use the sqrt function like this: math.sqrt(x)
The second method imports all the methods from math into the current namespace. You would use the sqrt function like this: sqrt(x)
Usually you want to use the first method, so you can avoid errors caused by functions having the same name.

April 20, 2016I may have been in math club, but the python Math module confuses me a little bit.
I have yet to really need it for a lot of things. Yes, maybe you can use the exponentiation operator ** to perform a square root, but there's a lot more in the math module than that. There's all the trig functions, hyperbolic functions as well as mathematical operations like factorial and GCD, not to mention the constants e, pi, tau, etc. If you need these things you need the math module. You just haven't needed them yet. More on reddit.com

Not exactly. ‘From math important *’ Says “bring the box of math tools and dump it out on the table with the rest of my tools.” Calls look like: ‘Thing_from_math()’ Whereas ‘import math’ says “bring me the box of math tools and I’ll grab the tools as I need them”. Calls should look like: ‘Math.thing_from_math()’ And finally: ‘From math import thing_from_math’ Says “bring me the box of math tools and only unpack the specific tools I asked for. Calls look like: ‘thing_from_math()’

This was thought to be the least confusing approach for the many Python users who do not want to introduce complex numbers. For those wanting functions with complex number support, use the cmath module and its included sqrt(), sin(), etc. functions instead of the regular math functions (cmath docs). >>> import cmath >>> cmath.sqrt(-1) 1j >>> cmath.sin(1j) 1.1752011936438014j
