81 * (16/25)^(x+2) + (3/5)^(2x+4) = 144 .....eq1
you can check option one by one in
check option (A) put x=1 in eq 1 , we ll get eq1 is not satisfied
check option (B) put x= -1 in eq 1 , we ll get eq1 is not satisfied
check option (C) put x=-2 in eq 1 , we ll get eq1 is not satisfied
then option (D) is correct ans
