Hi, is there any way to convert a small decimal number like 1.414213562 back to its radical form like back to the square root of 2?
Use your calculator.
If the number is the square root of something, then square the number to to transform it back to its radical form
Like, n = the number,
So, sqrt(n^2) is its radical form.
If n is cube root of something.
cuberoot(n^3) is its radical form.
etc...
You may do some rounding off if you are looking for integer inside the radical sign.
