Answer:
Option (a) is correct.
The simplified form of
is ![3ab^2\sqrt[3]{b}](https://tex.z-dn.net/?f=3ab%5E2%5Csqrt%5B3%5D%7Bb%7D)
Step-by-step explanation:
Given : ![\sqrt[3]{27a^3b^7}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27a%5E3b%5E7%7D)
We have to write the simplest form of given expression
Consider the given expression ![\sqrt[3]{27a^3b^7}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27a%5E3b%5E7%7D)
27 can be written as 3³
can be written as 
Thus, expression becomes,
![\sqrt[3]{27a^3b^7}=\sqrt[3]{3^3a^3b^6b^3b}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27a%5E3b%5E7%7D%3D%5Csqrt%5B3%5D%7B3%5E3a%5E3b%5E6b%5E3b%7D)
Thus, Simplify, we get,
![=3ab^2\sqrt[3]{b}](https://tex.z-dn.net/?f=%3D3ab%5E2%5Csqrt%5B3%5D%7Bb%7D)
Thus, The simplified form of
is ![3ab^2\sqrt[3]{b}](https://tex.z-dn.net/?f=3ab%5E2%5Csqrt%5B3%5D%7Bb%7D)
