Answer:
B
Step-by-step explanation:
Using the rules of radicals
[tex](a^{m)} ^{n}[/tex] = [tex]a^{mn}[/tex]
[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{a^{m} }[/tex]
Given
[tex](3x^2y^6)^{\frac{2}{7} }[/tex]
Square each term in the parenthesis the take the seventh root of the result
= [tex]\sqrt[7]{9x^2y^12}[/tex] → B
