Answer:
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.

Basically, a number when get multiplied by itself is called a square number. For example: 3 x 3 = 9 so 9 is a square number. You can see some more examples below:
16 = 4 x 4 = 42
64 = 8 x 8 = 82
49 = 7 x 7 = 72
36 = 6 x 6 = 62
In this article, we will learn to find the root of 4. This topic is widely explained in Class 8 syllabus, where square and the square root of different numbers have been determined. Let us see some basics related to square root.
