Math Problem Statement

how to simplify (8x with an exponent of 2 y) with an exponent of 1/3.

Solution

To simplify (8x2y)13(8x^2y)^{\frac{1}{3}}, follow these steps:

Step 1: Distribute the exponent 13\frac{1}{3} to each term inside the parentheses.

(8x2y)13=813(x2)13y13(8x^2y)^{\frac{1}{3}} = 8^{\frac{1}{3}} \cdot (x^2)^{\frac{1}{3}} \cdot y^{\frac{1}{3}}

Step 2: Simplify each part.

  1. 8138^{\frac{1}{3}} is the cube root of 8, which is 2. 813=28^{\frac{1}{3}} = 2

  2. (x2)13(x^2)^{\frac{1}{3}} simplifies by multiplying the exponents. (x2)13=x23(x^2)^{\frac{1}{3}} = x^{\frac{2}{3}}

  3. y13y^{\frac{1}{3}} remains as is.

Step 3: Combine the results.

2x23y132 \cdot x^{\frac{2}{3}} \cdot y^{\frac{1}{3}}

So, (8x2y)13=2x23y13(8x^2y)^{\frac{1}{3}} = 2x^{\frac{2}{3}}y^{\frac{1}{3}}.
