Radical x squared

The term or number whose square root is being radical x squared is known as the radicand. The radicand is the number or expression underneath the radical sign, radical x squared, in this case, 9. Although the principal square root of a positive number is only one of its two square roots, the designation " the square root" is often used to refer to the principal square root.

While it looks like you can just cancel out the squares with the square root, this only works if you have one square within the radical. Since we're adding two together, it's slightly different. The way that this expression CAN be simplified is by using polar coordinates, which are found in pre-calculus and above. Therefore, if we assume that the x and y this problem is using are the horizontal and vertical directions on a coordinate plane, we could technically rewrite our expression as:. Remember, this is probably NOT what your teacher is looking for, unless you're in pre-calculus or above. I would just stick with the original answer that the expression cannot be simplified.
