In Computer and Calculator

[jinsujais]

Hi

What is the basic principle or logic behind finding the square root or cube root in the calculator or in a computer.

[sakumar79]

Pocket calculators typically implement good routines to compute the exponential function and the natural logarithm, and then compute the square root of x using the identity sqrt(x)=exp(0.5* ln(x)). Similarly, cbrt(x)=exp(ln(x)/3)
