By exponential definition, we know that nam=amn

In this case, we can do the same for b, factoring it out:

8b211b299
However, we can see that 99=119, so

8b211b2119

However, 9 is a square number. Thus, we can take its root out of the square root.

8b2113b211

However, as both factors are multiplying b211, we can factor it in function of such elements:

b211(83)
