#### The formula for finding the **roots** of a quadratic equation can also be used to find the **square root of 1**. Let the **square** of the number ‘x’ be equal to ‘1’. This can be written as: x 2 = 1. x = 1. → (1) The above equation is a quadratic equation which can be represented in standard form as: x 2 + 0 x − 1 = 0. . Number **65536** is a **square** number with n=256. Binary numeral for number **65536** is 10000000000000000 . Octal numeral is 200000 . Duodecimal value is 31b14 . Hexadecimal representation is 10000. **Square** of the number **65536** is 4294967296 . **Square** **root** of the number **65536** is 256.

That’s all it takes! You can now use math.sqrt() to calculate

**square roots**.. sqrt() has a straightforward interface. It takes one parameter, x, which (as you saw before) stands for the**square**for which you are trying to calculate the**square root**.In the example from earlier, this would be 25.. The return value of sqrt() is the**square root**of x, as a floating point number.In the. To calculate the**square root**of a negative number, find the**square root**of the same positive number and multiply by "i". ( where i represents an imaginary number and i =**square root**of -1) Example:**square root**of -5. = (**square root**of 5) x (**square root**of -1) = (**square root**of 5) x (i) = 2.236068 x i. = 2.236068i. Calculator Use. Use this calculator to find the principal**square root**and**roots**of real numbers. Inputs for the radicand x can be positive or negative real numbers. The answer will also tell you if you entered a perfect**square**. The answer will show you the complex or imaginary solutions for**square roots**of negative real numbers.sonolus code
