To simplify the expression \( \sqrt[3]{500a^4b^6} \), we will first break it down.

  1. Factor the constants:

    • \( 500 = 5^3 \cdot 2 \) (since \( 500 = 125 \cdot 4 = 5^3 \times 2^2 \)).
  2. Break down the variables:

    • \( a^4 = a^{3+1} = a^3 \cdot a^1 \).
    • \( b^6 = (b^2)^3 \).

Now, we can rewrite the expression:

\[ \sqrt[3]{500a^4b^6} = \sqrt[3]{5^3 \cdot 2 \cdot a^3 \cdot a \cdot (b^2)^3} \]

Now apply the properties of cube roots:

\[ \sqrt[3]{5^3} = 5, \quad \sqrt[3]{a^3} = a, \quad \sqrt[3]{(b^2)^3} = b^2 \]

So we can simplify the expression:

\[ \sqrt[3]{500a^4b^6} = 5b^2a \sqrt[3]{2a} \]

Thus, the fully simplified expression is:

\[ 5ab^2 \sqrt[3]{2a} \]

Now, looking at your given choices, the closest simplified form is:

5ab² 4a−−√3 (assuming this means 5ab² 2√3).

However, it seems your multiple-choice options may not directly reflect the result I calculated or could contain formatting issues. Please ensure to double-check your options. If "4a" means "2a" in the expression context, that would validate the answer. Otherwise, please specify differently.
