When the square root of a number is squared, the result is the original number. The square root function is the inverse of the squaring function just as subtraction is the inverse of addition. To undo squaring, we take the square root. The square root could be positive or negative because multiplying two negative numbers gives a positive number. The square root obtained using a calculator is the principal square root. The symbol is called a radical , the term under the symbol is called the radicand , and the entire expression is called a radical expression.

A square root of is a number such that. When written in the form or especially , the square root of may also be called the radical or surd. The square root is therefore an n th root with. Note that any positive real number has two square roots, one positive and one negative. For example, the square roots of 9 are and , since. Any nonnegative real number has a unique nonnegative square root ; this is called the principal square root and is written or. For example, the principal square root of 9 is , while the other square root of 9 is.

Our square root calculator estimates the square root of any positive number you want. Just enter the chosen number and read the results. Everything is calculated quickly and automatically! With this tool, you can also estimate the square of the desired number just enter the value into the second field which may be a great help in finding perfect squares from the square root formula. Are you struggling with the basic arithmetic operations: adding square roots, subtracting square roots, multiplying square roots or dividing square roots? Not any more! In the following text, you will find a detailed explanation about different square root properties, e.

explanation. 16 = 4^2 and 49 = 7^2. +-sqrt(16/49) = +-sqrt(4^2/7^2) = +-4/7. Explanation: 16=42 and 49= ?. ±v=±v=±
