[Type C] Working with Functions – Chapter 3 Sumita Arora

6. Write a function named nthRoot() that receives two parameters x and n and returns the nth root of x, i.e., x^(1/n). The default value of n is 2.

Short Answer: The function nthRoot() will calculate the nth root of a number. It takes two parameters, x and n, where x is the number and n is the root. If n is not provided, it defaults to 2.

def nthRoot(x, n=2):
    return x ** (1/n)

# Test
print(nthRoot(16))  # 4.0 (Default value of n is 2)
print(nthRoot(27, 3))  # 3.0

Explanation:

• The function nthRoot calculates the nth root of a number using the exponentiation operator **.
• It takes two parameters, x (the number) and n (the root), with n defaulting to 2.
• Test cases demonstrate how to use the function with both default and custom values for n.
