If GCD(a,b)=1\text{GCD}(a, b) = 1GCD(a,b)=1, which of the following is true regarding a2a^2a2 and b2b^2b2?
GCD(a2,b2)=0\text{GCD}(a^2, b^2) = 0GCD(a2,b2)=0
GCD(a2,b2)=a2\text{GCD}(a^2, b^2) = a^2GCD(a2,b2)=a2
GCD(a2,b2)=1\text{GCD}(a^2, b^2) = 1GCD(a2,b2)=1
GCD(a2,b2)=a+b\text{GCD}(a^2, b^2) = a+bGCD(a2,b2)=a+b
