## What is sqrt formula?

The square root of any number can be expressed using the formula: ?y = y. In other words, if a number has 1/2 as its exponent, it means we need to find the square root of the number.

## What is an example of a square root function?

The standard form of a square root function is the square root with all the transformations shown. y=a?x?h+k,where a,h,k are all real numbers. When we multiply the function by a positive constant, like a, we change the size of the function, i.e., a dilation.
