There are 2 possible roots for any positive real number. A positive root and a negative root. Given a number x, the square root of x is a number a such that a2 = x. Square roots is a specialized form of our common roots calculator. "Note that any positive real number has two square roots, one positive and one negative. For example, the square roots...
This calculator will also tell you if the number you entered is a perfect square or is not a perfect square. A perfect square is a number x where the square root of x is a number a such that a2 = xand a is an integer. For example, 4, 9 and 16 are perfect squares since their square roots, 2, 3 and 4, respectively, are integers.
The 2nd root of 81, or 81 radical 2, or the square root of 81 is written as 812=81=±9.The 2nd root of 25, or 25 radical 2, or the square root of 25 is written as 252=25=±5.The 2nd root of 100, or 100 radical 2, or the square root of 100 is written as 1002=100=±10.The 2nd root of 10, or 10 radical 2, or the square root of 10 is written as 102=10=±3.162278.If this is the case, our square root calculator is the best option to estimate the value of every square root you desire. For example, let's say you want to know whether 4√5 is greater than 9. From the calculator, you know that √5 ≈ 2.23607, so 4√5 ≈ 4 × 2.23607 = 8.94428.
Checking the outcome against the square root calculator output of 5.477226 reveals that the algorithm resulted in a correct solution. While the above process can be fairly tedious especially with larger roots, but will help you find the square root of any number with the desired decimal precision. Properties and practical application of square ...
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.

Square Root Calculator. Every nonnegative real number a has a unique nonnegative square root, called the principal square root, which is denoted by √ a, where √ is called the radical sign or radix. For example, the principal square root of 9 is 3, denoted √ 9 = 3. √. = ? Calculator to give out the square root result of a positive number.
The calculator on this page will indicate whether the input number is a perfect square. Square roots. The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square roots of 9 are 3 and -3, since 3 × 3 = 9, and (-3) × (-3) = 9, therefore, (-3)² = 3² = 9. Similarly, the square roots ...
