If a and b are coprime, then $$a^2\, and \,b^2$$​are-

Correct option is A

Solution:

Two numbers are said to be coprime if their greatest common divisor (GCD) is 1. In other words, they share no common prime factors. If $a$ and $b$ are coprime, squaring them does not introduce any new common factors. Therefore, $$a^2 \, and \, b^2$$​will also have no common factors and will remain coprime.

Hence, $$a^2 \, and \, b^2$$are coprime.
