Is the square root of 32 a rational number

Rational numbers can be written fully in the form a/b where b is not equal zero

so examples of rational numbers
2/1, 2/3
pi is not since pi represents the full one and is not written fully
 √32=√16 times √2=4 times √2
since √2 is irrational, the whole number is irratnioal

the answer is it is not a rational number

Ibelieve the second one, but if not, the first one will do. hope this : )
