Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Simplify the fraction within the square root, if possible.
  • Step 2: Apply the square root quotient property ab=ab\sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}}.
  • Step 3: Calculate the square roots of the resulting numbers.
  • Step 4: Simplify the fraction, if necessary.

Now, let's work through each step:

Step 1: Simplify the fraction 936\frac{9}{36}.
We notice that both 9 and 36 have a common factor of 9. So, we simplify:

936=14\frac{9}{36} = \frac{1}{4}

Step 2: Apply the square root quotient property:

936=14\sqrt{\frac{9}{36}} = \sqrt{\frac{1}{4}}

Now address the square root of the simplified fraction:

14=14\sqrt{\frac{1}{4}} = \frac{\sqrt{1}}{\sqrt{4}}

Step 3: Calculate the square roots:

1=1\sqrt{1} = 1
4=2\sqrt{4} = 2

Step 4: Simplify the fraction:

12\frac{1}{2}

Therefore, the solution to the problem is 12\frac{1}{2}.

Answer

12 \frac{1}{2}
