What is R mean in math?

Simplifying the roots of a polynomial is no easy task. The radical symbol, the R, does just that. The radical of a number is the square root of the number. It's another way of solving the square root problem. If you have a radical inside an exponent, the radical is raised to the exponent. For example, the radical of 2 is which equals If you have a radical inside an exponent, the radical is raised to the exponent. For example, the radical
