Math Problem Statement

simplify the cube root of 10 times square root of 5

Solution

To simplify 103×5\sqrt[3]{10} \times \sqrt{5}, follow these steps:

Step 1: Combine the expressions under the cube root and square root.

You have 103×5\sqrt[3]{10} \times \sqrt{5}, which involves a cube root and a square root. You can express both terms as exponents:

  • 103=101/3\sqrt[3]{10} = 10^{1/3}
  • 5=51/2\sqrt{5} = 5^{1/2}

Thus, the expression becomes: 101/3×51/210^{1/3} \times 5^{1/2}

Step 2: Keep the terms separate.

Since these two terms have different bases, we cannot directly combine them into one root or exponent without further manipulation. Therefore, we leave the expression as: 101/3×51/210^{1/3} \times 5^{1/2}

Step 3: Approximate if needed.

If you're looking for an approximation, you can evaluate the expression numerically. Here's how:

101/32.154and51/22.23610^{1/3} \approx 2.154 \quad \text{and} \quad 5^{1/2} \approx 2.236

Multiplying these gives: 2.154×2.2364.812.154 \times 2.236 \approx 4.81

Final Answer:

The simplified form of the expression remains 101/3×51/210^{1/3} \times 5^{1/2}, or approximately 4.81.
