Square Root Calculator

You must be familiar with square roots if you are a math student. Any value's square root is just the amount that, when multiplied by itself, equals the initial digit. For illustration: 3.16 is the square root of 10. The square root calculator is a free online tool that displays the square root of a given number. The Mathematics Master online square root calculator makes the calculation fast by calculating the square root of a given value in milliseconds.

\( \sqrt{x} = ? \)

Square Root symbol

The square root symbol or square root sign is denoted by ‘\(√\)’. In other words, this symbol is called radical.

How to Use the Square Root Calculator?

The square root calculator should be used as follows:

  • First, enter the appropriate input field’s corresponding number.
  • Then, click the “Find Square Root” button to obtain the result.
  • The output field will show the specified number’s square root.

Square Roots, odd and even

Any positive real number has two potential positive and negative roots. The square root of a number x is a number a such that \(a^2 = x\). A more specialized version of our common roots calculator is square roots.

Perfect Square Calculator

A number x is a perfect square if and only if its square root, a, is an integer and \(a^2 = x\). For instance, 4, 9, and 16 are perfect squares since their corresponding square roots, 2, 3, and 4 are integers.


How to find square roots without a calculator?

  • Imagine you need to determine the square root of 20. You are aware that the square root of \(4 (4×4=16)\) makes the number 16 a perfect square. The square root of 20 must be between 4 and 5, so 25 has a square root of \(5 (5×5=25)\).
  • You might infer that the square root of 20 is 4.5. Enter square 4.5 to verify your prediction. \(4.5×4.5\) is the result of multiplying it by itself. See if the answer is higher or lower than 20. Attempt another number (perhaps 4.6 or 4.4) and continue to hone your guess until you reach 20.

What is the formula for square root?

The formula for a number’s square root is as: \( \sqrt{(x^2)} = x\).

What is the square root of 2?

You can use long division to determine the square root of 2 because the integer is not a perfect square. A rough equivalent is 1.414.
