Math Problem Statement

Simplify the expression \( \sqrt{\frac{\sqrt{3} - 3}{\sqrt[3]{8}} + 4.5\sqrt[3]{5}} \cdot \sqrt[3]{2} \).

Solution

The mathematical problem in the image appears to involve nested radicals and a product of square roots. I will transcribe the expression and solve it step by step.

The expression appears to be:

[ \sqrt{\frac{\sqrt{3} - 3}{\sqrt[3]{8}} + 4.5\sqrt[3]{5}} \cdot \sqrt[3]{2} ]

Solution:

Step 1: Simplify each component.

  1. 83=2\sqrt[3]{8} = 2, since 23=82^3 = 8.
  2. Rewrite the fraction: 3383=332.\frac{\sqrt{3} - 3}{\sqrt[3]{8}} = \frac{\sqrt{3} - 3}{2}.
  3. Rewrite 4.5534.5 \sqrt[3]{5} as-is since it doesn't simplify further: 4.553.4.5 \sqrt[3]{5}.

Step 2: Combine terms inside the square root.

The expression under the square root becomes: 332+4.553.\sqrt{\frac{\sqrt{3} - 3}{2} + 4.5\sqrt[3]{5}}.

Step 3: Multiply by 23\sqrt[3]{2}.

The final expression after including the product becomes: [ \sqrt{\frac{\sqrt{3} - 3}{2} + 4.5\sqrt[3]{5}} \cdot \sqrt[3]{2}. ]

Step 4: Evaluate numerically (optional).

If you want, I can evaluate this numerically, but the expression above is its simplified form.

Would you like to proceed with a numerical evaluation, or do you want further clarification on any part of this process?
