Square Root Formula

Square Root Formula

The square root of a number x is a number y such that y² = x. In mathematical terms:

√x = y

where y² = x

The iPhone calculator uses this formula to compute square roots. It can handle both perfect squares (like 16, which has a whole number square root) and non-perfect squares (like 25.92, which has a decimal square root).
