Question

125^1/2×5^1/2-216^1/3

Answer 1

${125}^{ \frac{1}{2} } = \sqrt{125}$
${5}^{ \frac{1}{2} } = \sqrt{5}$
$\sqrt{125 \times 5} = \sqrt{625}$
$\sqrt{625} = 25$
${216}^{ \frac{1}{3} } = \sqrt[3]{216}$
$\sqrt[3]{216} = 6$
$25 - 6 = 19$

Answer 2

To solve this expression, let's break it down step by step:

1. Calculate the square root of 125: √125 = 11.18034 (rounded to five decimal places)

2. Calculate the square root of 5: √5 = 2.23607 (rounded to five decimal places)

3. Now, multiply the square roots of 125 and 5: 11.18034 × 2.23607 ≈ 24.99494 (rounded to five decimal places)

4. Calculate the cube root of 216: ∛216 = 6 (because 6^3 = 216)

5. Finally, subtract the cube root of 216 from the previous result: 24.99494 - 6 ≈ 18.99494 (rounded to five decimal places)

So, the value of the expression is approximately 18.99494.
