Math Problem Statement

Simplify the expression \(\sqrt[3]{24x^8y^6}\).

Solution

The given expression is the cube root of 24x8y624x^8y^6. We will simplify this step by step:

Expression:

24x8y63\sqrt[3]{24x^8y^6}

Step 1: Factor the constant inside the cube root

First, we simplify the constant 2424 by factoring it: 24=23×324 = 2^3 \times 3 So, the expression becomes: 23×3×x8×y63\sqrt[3]{2^3 \times 3 \times x^8 \times y^6}

Step 2: Apply cube root to each factor

We can now apply the cube root to each part: [ \sqrt[3]{2^3} \times \sqrt[3]{3} \times \sqrt[3]{x^8} \times \sqrt[3]{y^6} ]

  1. 233=2\sqrt[3]{2^3} = 2
  2. 33\sqrt[3]{3} remains as 33\sqrt[3]{3} since 3 is not a perfect cube.
  3. x83=x8/3=x2×x2/3\sqrt[3]{x^8} = x^{8/3} = x^2 \times x^{2/3}
  4. y63=y6/3=y2\sqrt[3]{y^6} = y^{6/3} = y^2

Step 3: Combine the simplified terms

The final simplified expression is: 2x2y2×3x232x^2y^2 \times \sqrt[3]{3x^2}

So, the simplified form of 24x8y63\sqrt[3]{24x^8y^6} is: 2x2y23x232x^2y^2 \cdot \sqrt[3]{3x^2}
