Step-by-step solution

To solve this problem, we will systematically apply the properties of square roots and perform the arithmetic operations:

  • Step 1: Calculate 100\sqrt{100}.
  • Step 2: Calculate the individual square roots 25\sqrt{25} and 4\sqrt{4}, and then multiply them.
  • Step 3: Divide the result from Step 1 by the product of Step 2.

Now, let's work through each step:

Step 1: The square root of 100 is 10, since 10×10=10010 \times 10 = 100. Therefore, 100=10\sqrt{100} = 10.

Step 2: Calculate 25\sqrt{25} and 4\sqrt{4}. We know 25=5\sqrt{25} = 5 because 5×5=255 \times 5 = 25, and 4=2\sqrt{4} = 2 because 2×2=42 \times 2 = 4. Thus, the product is 254=52=10\sqrt{25} \cdot \sqrt{4} = 5 \cdot 2 = 10.

Step 3: Divide the result from Step 1 by the product from Step 2: 100254=1010\frac{\sqrt{100}}{\sqrt{25} \cdot \sqrt{4}} = \frac{10}{10}.

Therefore, the simplified expression is 1 1 .

As a result, the answer to the problem is 1 1 .
