Answer:
[tex]-9a^3b^2[/tex]
Step-by-step explanation:
Given : [tex]-729a^9b^6[/tex]
To Find : find cube root
Solution:
[tex]\sqrt[3]{-729a^9b^6}[/tex]
[tex](-729a^9b^6)^{\frac{1}{3}}[/tex]
[tex](-9^3a^9b^6)^{\frac{1}{3}}[/tex]
[tex]-9a^3b^2[/tex]
Hence the cube root of [tex]-729a^9b^6[/tex] is [tex]-9a^3b^2[/tex]
