This calculator is a two in one, it calculates both square roots and cube roots of numbers. .
A squareroot of a number b, is a number x such that x2 = b, which means, a number x whose square that is the result of multiplying the number by itself, or x × x is b.
For example, 5 and −5 are squareroots of 25 because 5² = (−5)² = 25.
Every non negative real number c has a unique non negative squareroot, called the principal, which is denoted by √c, where √ is called the radical sign or radix. For example, the principal squareroot of 36 is 6, denoted √36 = 6, because 6² = 6 × 6 = 36 and 6 is non negative. The no whose root is being considered is known as the radicand. The radicand is the number or expression underneath the radical sign, in this example 36.
Every positive number a has two roots: √b, which is positive, and −√b, which is negative. These two roots are denoted ± √b. The principal root of a positive number is only one of its two squareroots, the designation "the square root" is often used to refer to the principal root. For positive b, the principal squareroot can also be written in exponent notation, as b1/2.
