Which of the following is true about the math module in Python?

It is part of the standard library and provides mathematical functions.

It must be imported using 'from math import *' to be used.

It is only available in Python 3.10 and later.

It is a third-party module that must be installed separately.

A scientific application needs to compute the number of possible orderings of 20 distinct items. The developer writes a function that uses math.factorial(20). However, the result is used in a formula that also requires the square root of the factorial. Which expression correctly computes the square root of 20! using the math module?

math.factorial(20) / math.sqrt(20)

math.sqrt(20) * math.factorial(20)
