Question
If p and q are co-prime numbers, then p2 and q2 are
Options
coprime
not coprime
even
odd
Solution
We know that the co-prime numbers have no factor in common, or, their HCF is 1.
Thus, `p^2` and `q^2` have the same factors with twice of the exponents of p and q respectively, which again will not have any common factor.
Thus we can conclude that `p^2` and `q^2` are co-prime numbers.
Hence, the correct choice is (a).
