In this mini lesson, we will learn about the square root of 123 and find out whether the square root of 123 is rational or irrational
We will also learn how to find the square root of 123 by long division method.
Tool to compute and simplify a square root The square root for a number n, is the number noted sqrt (n) that, multiplied by itself, equals n. What is the square root of 123 The square root of 123 is ±11.0905365, where 11.0905365 is the positive solution of the equation x 2 = 123
Finding the square root is just the inverse of squaring a number and hence, squaring 11.0905365 will result in 123. As the index 2 is even and 123 is greater than 0, 123 has two real square roots Therefore, solving for the square root of 123, we find that the square root of 123 is 11.091 Your answer can be either a whole number or a decimal.
