The last question is, why is the square root operation called root regardless of its true origin? The explanation should become more evident if we write the equation x = ⁿ√a in a different form: xⁿ = a. x is called a root or radical because it is the hidden base of a. Thus...

Square root of a non-perfect square number in the simplest radical form can be found using prime factorization method. For example: 72 = 2 × 2 × 2 × 3 × 3. So, √72 = √(2 × 2 × 2 × 3 × 3) = 6√2.How to Find the Square Root of 72?There...
The square root of 360 is 18.973 approximated to 3 decimal places. The simplified form of 360 in its radical form is 6√10. √360 is an irrational number. Challenging Questions What will be the least number multiplied and divided to 360 to make it perfect square?
In this case, 8 is the radicand and 2√2 is the simplest and the radical form of √8. This value is called surd since you cannot simplify this further. Is Root 8 a Perfect Square? Even though 8 is not a prime number, yet, when we take its square root, we get 2 as its only...
