If you choose to fully simplify this expression, then the answer is b^3
If you just want to convert to rational exponent form, then the square root will be replaced with an exponent of 1/2. The rule is sqrt(x) = x^(1/2)
So,
sqrt(b^6) = (b^6)^(1/2)
which can be written as
note how the exponents 6 and 1/2 multiply to 3, which is why the fully simplified version is b^3
There are many ways. 
is actually the same as 
so anything you do just has to have a numerator exactly half as the denominator. So one that would work is 
I just doubled both numbers. Other ones would be 
all of which the numerator is exactly half the denominator.
