You have the equation given in the problem:
Then base of is 2. Therefore, the common base must be 2.
If you add 3 to both sides of the equation, you obtain:
If you descompose 8 into its prime factors, you obtain that it can be written as:
8=2*2*2=2³
Therefore, you can you rewrite each side of the equation as following:
Where the common base is 2.
