Math Problem Statement

Can you simplify this problem

Can you simplify the expression (∛125 / 512)^(1/3)?

Solution

Let's analyze and simplify the expression from the image. The given expression is:

(1253512)13\left(\frac{\sqrt[3]{125}}{512}\right)^{\frac{1}{3}}

To simplify, let's proceed step by step:

  1. Evaluate 1253\sqrt[3]{125}:

    • Since 125=53125 = 5^3, we have 1253=5\sqrt[3]{125} = 5.

    So the expression simplifies to:

    (5512)13\left(\frac{5}{512}\right)^{\frac{1}{3}}

  2. Evaluate (5512)13(\frac{5}{512})^{\frac{1}{3}}:

    • We can write this as: 535123\frac{\sqrt[3]{5}}{\sqrt[3]{512}}.
    • Since 512=29512 = 2^9, we have 5123=23=8\sqrt[3]{512} = 2^3 = 8.

    Therefore, the expression becomes:

    538\frac{\sqrt[3]{5}}{8}

Thus, the simplified form of the expression is:

538\boxed{\frac{\sqrt[3]{5}}{8}}
