Second Question for function challenges

Hello everyone, I am on the second challenge for functions and I think I found an error perhaps. The question wants me to use (**) to find the square root of the argument (num). However from the previous lessons codecademy only has explained how to use (**) as a power for an argument ex: num**2. Please explain to me how you can find the square root of an argument using (**).

Write a function named `square_root()`

that has one parameter named `num`

.

Use exponents ( `**`

) to return the square root of `num`

.

# Write your square_root function here:

def square_root(num):

result = num**;

return result

# Uncomment these function calls to test your square_root function:

print(square_root(16))

# should print 4

print(square_root(100))
