Step-by-Step Solution

To solve the problem 1030100\frac{\sqrt{10} \cdot \sqrt{30}}{\sqrt{100}}, we'll use the rules of square roots, specifically the multiplication and division properties.

Start by simplifying the numerator using the multiplication property of square roots:

  • 1030=10×30=300\sqrt{10} \cdot \sqrt{30} = \sqrt{10 \times 30} = \sqrt{300}

Next, we simplify the entire fraction using the division property of square roots:

  • 300100=300100=3\frac{\sqrt{300}}{\sqrt{100}} = \sqrt{\frac{300}{100}} = \sqrt{3}

Thus, the simplified form of the expression 1030100\frac{\sqrt{10} \cdot \sqrt{30}}{\sqrt{100}} is 3\sqrt{3}.

Therefore, the solution to the problem is 3 \sqrt{3} .

Answer

3 \sqrt{3}
