Radicand

No, you cannot add or subtract under the radical. The radical represents the square root function, and it only operates on the number or expression that is inside the radical. To add or subtract, you need to simplify the expressions inside the radical first.

A radical number is a number with a decimal. so a radical expression would be like 5 raised to the 2.5 power.

The answer depends on the form of the radical expression.

Radicand

The term radicand means the number or expression inside the radical symbol. For example, when we have the square root of 2, the 2 is inside the radical symbol. It is the radicand. The radicand may be a number or an algebraic expression. Also, there is not limit to the number of terms the radicand may contain. It may even be infinite!
