Answer 2

The value of under root 484 (√484 ) is 22.

• Under root 484 means √484 (square root of 484) .

• The first step to finding the square root of a number is to find its L.C.M and get all the factors.

• The L.C.M. of 484 gives the factors as 2 × 2 × 11 × 11 (refer to the image attached below) .

• Sqaure means twice of a number. Therefore, to arrive at the square root a number, two common factors have to be taken as one.

• For 484, two 2's have to be taken as one, and two 11's have to be taken as one.

=> The square root of 484 is 2 × 11 = 22

• ∴  √484 = 22
