Question

What is a perfect square radicand?

Answer 1

Hint: We know that the square root of a number is denoted by \[\sqrt a \] . Here ‘a’ is called radicand. We know that the perfect square is defined as a natural number that is multiplied by itself. Below we will know what a perfect square radicand is.

Complete step-by-step answer:
We know that in this \[\sqrt a \] is called radicand.
A perfect square radicand has a square root that is an exact number. Let’s see some perfect square radicand. Those are 4. 16, 25, 36 and so on.
Because \[\sqrt 4 = 2,\sqrt {16} = 4,\sqrt {25} = 5,\sqrt {36} = 6\] ….
Hence the above are the examples of perfect square radicand.

Note: When a square root is multiplied, it produces a square number. Thus a square root has an inverse operation than the square number. That square of a number and square root of that number will cancel out. We also know that the square of negative numbers results in positive numbers.
