Answer:
√125a^3b^3
I just took the test and this was the correct answer.
Step-by-step explanation:
1. Radical "equation"- [tex]b^{\frac{m}{n} = \sqrt[n]{b} ^{m} \\[/tex]
[tex](5ab)^{\frac{3}{2} } = \sqrt[2]{5}^{3} \\\sqrt[2]{5}^{3}{a}^{3}{b}^{3} \\\\{5}^{3}= 125 \\\sqrt{125}{a}^{3}{b}^{3}[/tex]
Ignore that "AA" thing, I don't know what that is.
