Step-by-step explanation: A composite number is defined to be a number which has other divisors besides 1 and the number itself. Start counting:1, 2, 3, 4, 5, 6……….
1 is not a composite number because its sole divisor is 1. 2 is not a composite number because it has only two divisors 1 and the number 2 itself. 3 is in the same class as 2.
But 4 is different. Its divisors are 1,2,4. So this number satisfies the criterion of a composite number as stated above since besides 1 and 4, 2 is also a divisor. 4 is also the smallest composite number. The next composite number after 4 is 6 which has as divisors 1,2,3,6.

Statement: ALL square roots are irrational numbers.
Irrational is defined as a non-terminating real number.
✓4 = 2
2 is a terminating real number.
Therefore, 2 is rational.
The square root of 4 results in 2.
Therefore the square root of 4 results in a rational number.
Hence not all square roots result in irrational numbers.
