Cara menggunakan python cube root integer

Python Basic - 1: Exercise-146 with Solution

A Python list contains two positive integers. Write a Python program to check whether the cube root of the first number is equal to the square root of the second number.

Sample Data:

([8, 4]) -> True
([64, 16]) -> True
([64, 36]) -> False

Sample Solution-1:

Python Code:

def test(nums):
    x = nums[0]
    y = nums[1]
    t = y**0.5
    if(x == t*t*t):
        return True
    else:
        return False         
nums = [8, 4]
print("Original list of positive numbers:")
print(nums)
print(test(nums))
print("Check square root and cube root of the said numbers:")
nums = [64, 16]
print("Original list of positive numbers:")
print(nums)
print("Check square root and cube root of the said numbers:")
print(test(nums))
nums = [64, 36]
print("Original list of positive numbers:")
print(nums)
print("Check square root and cube root of the said numbers:")
print(test(nums)) 

Sample Output:

Original list of positive numbers:
[8, 4]
True
Check square root and cube root of the said numbers:
Original list of positive numbers:
[64, 16]
Check square root and cube root of the said numbers:
True
Original list of positive numbers:
[64, 36]
Check square root and cube root of the said numbers:
False

Sample Solution-2:

Python Code:

def test(nums):
	return (((nums[1] ** 0.5) ** 3) == nums[0])

nums = [8, 4]
print("Original list of positive numbers:")
print(nums)
print(test(nums))
print("Check square root and cube root of the said numbers:")
nums = [64, 16]
print("Original list of positive numbers:")
print(nums)
print("Check square root and cube root of the said numbers:")
print(test(nums))
nums = [64, 36]
print("Original list of positive numbers:")
print(nums)
print("Check square root and cube root of the said numbers:")
print(test(nums)) 

Sample Output:

Original list of positive numbers:
[8, 4]
True
Check square root and cube root of the said numbers:
Original list of positive numbers:
[64, 16]
Check square root and cube root of the said numbers:
True
Original list of positive numbers:
[64, 36]
Check square root and cube root of the said numbers:
False

Given a number, the task is to write a Python program to calculate square of the given number.

Examples:

Input: 4
Output: 16

Input: 3
Output: 9

Input: 10
Output: 100

We will provide the number, and we will get the square of that number as output. We have three ways to do so:

• Multiplying the number to get the square (N * N)
• Using Exponent Operator
• Using math.pow() Method

Method 1: Multiplication

In this approach, we will multiply the number with one another to get the square of the number.

Example:

Python3

n = 4

square = n * n

print(square)

Output:

16

Method 2: Using Exponent Operator

In this approach, we use the exponent operator to find the square of the number.

Exponent Operator: **

Return: a ** b will return a raised to power b as output.

Example:

Python3

n = 4

square = n ** 2

print(square)

Output:

16

Method 3: Using pow() Method

In this approach, we will use the pow() method to find the square of the number. This function computes x**y and returns a float value as output.

Syntax: float pow(x,y)

Parameters :

x : Number whose power has to be calculated.

y : Value raised to compute power.
 

Return Value : 
Returns the value x**y in float.

Example:

Python3

n = 4

square = pow(n, 2)

print(square)

Output:

16.0
