Math Problem Statement

Simplify the expression: 2 * cube root(4) * (cube root(2) + cube root(16))

Solution

The expression in the image is:

[ 2 \sqrt[3]{4} \left( \sqrt[3]{2} + \sqrt[3]{16} \right) ]

Let's break it down step by step:

  1. Evaluate each cube root:

    • 431.5874\sqrt[3]{4} \approx 1.5874
    • 231.2599\sqrt[3]{2} \approx 1.2599
    • 163=243=2232×1.2599=2.5198\sqrt[3]{16} = \sqrt[3]{2^4} = 2 \sqrt[3]{2} \approx 2 \times 1.2599 = 2.5198
  2. Simplify the terms inside the brackets: [ \sqrt[3]{2} + \sqrt[3]{16} \approx 1.2599 + 2.5198 = 3.7797 ]

  3. Multiply by 2432 \sqrt[3]{4}: 2×1.5874×3.779712.0032 \times 1.5874 \times 3.7797 \approx 12.003

Thus, the simplified value of the expression is approximately 1212.

  2. How would this calculation change if the exponent was a square root instead of a cube root?
  3. Can this expression be rewritten using fractional exponents?
  4. What happens if you cube the result to reverse the operations?
  5. How does the calculation differ if the constants were inside the cube root?

Tip: When working with cube roots, it can be helpful to approximate the values of small numbers or express them using known powers for more precision.
