Newton's 2nd Law is the real Law of motion as it contains both the first and third Law. The outcomes of Newton's 1st Law are inertia and definition of fore, while the 2nd Law allows us to measure the force.
According to 2nd Law, we have F=ma.
Now, if no external force is applied on the body, then F=0. So, we have ma=0.
Since m is not equal to zero, a=0.
Thus, there will be no acceleration of the body if no external force is applied. It means that a body at rest will remain at rest and a body in uniform motion will continue moving uniformly along the same straight line in the absence of an external force. It is what is stated by the first Law of motion.
Hence the first Law is contained in the Second Law.
