The square root is the area in which you take 1 length and you multiply that number times the same number and you have your square root. The square you put it on graph paper and you size is going to be 3x3 then you connect the dots and count how may squares you have and that is your answer.There is an inverse relationship. If one number is the square of another then the second number is the square root of the first number.
perfect squares
It's between 2 and 3. You know this because the next two surrounding perfects squares are 4 and 9, which have square roots of 2 and 3 respectively.
They are called perfect squares.
169 and 196 are perfect squares. Their square roots are 13 and 14 respectively. The perfect squares from 1^2 to 16^2 are: 1,4, 9, 16, 25, 36, 49, 64, 81, 100, 144, 169, 196, 225, 256. It is useful to memorize the perfect squares, as it makes estimating square roots easier. In case you wanted to find the square root of 169,196, the answer is roughly 411.334414... The square roots of integers which are not perfect squares are irrational, so they can not be expressed exactly as a sequence of digits.
