Is the square root of every composite number a rational number ? Explain

Sagot :

The square root of a composite number is not always an irrational number.
ex. 4 is a composite number and its square root is 41/2 = 2, which is rational number.
ex. Square root of 6 is irrational.

if your "composite number" is not a perfect square, then its square root is irrational.

Many square roots are irrational numbers, meaning there is no rational number equivalent.
