2. Using math.sqrt() Method. import math number = int(input(“enter a number:”)) sqrt = math.sqrt(number) print(“square root:” , sqrt)
3. Using math.pow() Method.

What is the correct way to calculate square root of a number in C++?

Square root in C++ can be calculated using sqrt() function defined in h> header file. sqrt() function takes a number as an argument and returns the square root of that number.

How is square root calculated?

Here are the steps to the long division method:

1. Separate your square root base into pairs.
2. Find the largest square that divides into the first number or pair.
3. Subtract the square from the first number or pair.
4. Drop down the next pair.
5. Multiply the first digit of the square by two.

What is a positive square root?

A square root of a number b is a solution of the equation x2=b . The positive square root is the principal square root and is written √b . To denote the negative root, write −√b and to indicate both roots write ±√b .

How do you code a square in Python?

To calculate the square of a number in Python, we have three different ways.

1. By multiplying numbers two times: (number*number)
2. By using Exponent Operator (**): (number**2)
3. Using math.pow() method: (math.pow(number, 2))

Can the square root of a positive number be negative?

As shown earlier, a negative square root is one of two square roots of a positive number. For the number 25, its negative square root is -5 because (-5)^2 = 25. We can solve certain equations by finding the square root of a number. Let’s consider the equation of x^2 = 121.

How are the two square roots of a positive number related?

Answer: A positive number has two square roots because a positive number multiplied by itself is positive and a negative number multiplied by itself is also positive.
