How do you write square roots? A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand. To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root.

What is root4?

The value of root 4 is equal to exactly 2. But the roots could be positive or negative or we can say there are always two roots for any given number. Hence, root 4 is equal to ±2 or +2 and -2 (positive 2 and negative 2). You can also find square root on a calculator.
