What is inside the square root? Just the or the whole fraction ? Please put parentheses around radicands (the expression within a radical is called a radicand) so we can see what is inside a square root.

Without knowing what is in the square root I cannot answer the question. But I can give you some guidance:
  1. Change the square root to a power of 1/2. For example:
  2. Use your rules for exponents to simplify the expression down to "b" to some power. At this point you may already know what the answer is. If not...
  3. Use the property of logarithms to move the exponent of b out in front of the log. For example:
  4. You now have some number times . You should that any log where the base and the argument are the same is equal to 1. So the whole expression simplifies to just the number in front. For example:
