We understand that addition has one inverse procedure in subtraction and also multiplication has actually an inverse procedure in the division. Similarly, finding the square root is an inverse operation of squaring. The square source of 121 is the number that gets multiplied to chin to give the number 121.


A reasonable number is a number that can be to express in the type of p/q, where p and q are integers and also q is no equal to 0. We already found that 121 = 11. The number 11 is a reasonable number. So, the square root of 121 is a rational number.

How to uncover the Square source of 121?

We will comment on two techniques of detect the square source of 121

Prime FactorizationLong division

Square root of 121 By prime Factorization

Prime administer is a way of to express a number together a product of its prime factors. The prime factorization of 121 is 121 = 11 × 11 = 112. To discover the square source of 121, we take one number from every pair of the exact same numbers and also we multiply them.

121 = 11 × 11 121 = 11

Square source of 121 By Long Division


The value of the square source of 121 by long department method consists of the complying with steps:

Step 1: starting from the right, we will pair increase the number by placing a bar over them.Step 2: find a number which, once multiplied come itself, gives the product much less than or same to 1. So, the number is 1. Putting the divisor as 1, we obtain the quotient together 1 and the remainder 0Step 3: double the divisor and enter it through a empty on its right. Assumption: v the largest feasible digit to to fill the blank which will additionally become the new digit in the quotient, together that once the new divisor is multiplied to the brand-new quotient the product is much less than or equal to the dividend. Divide and also write the remainder.
