Square Root of 4 by Guess and Check Method

In the Guess and Check method, we generally make a initial guess and then think it wisely and try to refine to get a number that is bit closer to the actual value.

Step 1: Begin by making an initial guess for the square root of the given number. As this depends on your understanding on perfect squares.

Step 2: Square your first guess, then multiply that number and check whether you find you number or not, If not then U need to move to next step. Either you got your answer.

Step 3: If the result is too large, then you choose a large number you should think less than that number vice versa.

Step 4: We need to repeat your process until you get your original number.

Step 5: Once you got your special number for the original number, then you should check by multiplying by itself. Once you confirm, You should think you had done a perfect approximation.

Now, Lets apply these steps for finding Square root of 4,

Step 1: Let’s start with the guess √4 = 2.

Step 2: check whether when we multiply by itself it gives original number or not as 2 × 2 = 4, so I got my original number.

Step 3: So, We got square root of 4 by Guess and Check Method.

Square Root of 4 is equal to 2. It is represented as √(4) or (4)^1/2. The Square Root of a number is defined as the number that when multiplied by itself gives the original number.

In this article, we will learn what is the value of the square root of 4, how to find the value of the square root of 4.
