#### Answer

The statement does not make sense.

#### Work Step by Step

Consider the given number. ${{2}^{57885162}}-1$ The number in the power has $2$ at its one place thereby making it divisible by $2$. So, it is not prime. For ${{2}^{p}}-1$ to be prime, number $p$ needs to be prime. Thus, the number ${{2}^{57885162}}-1$ is not prime as $57885162$ is composite. Thus, the given statement is not true. The statement does not make sense.
