Answer:
Option a
Step-by-step explanation:
Given is an expression
[tex]343x^9v^{12} z^6[/tex]
We have to find the cube root of this expression.
This is product of constant and 3 variables.
So let us find cube root for each separately and multiply at last to get the answer.
[tex]\sqrt[3]{343} =7\\\sqrt[3]{x^9} =x^3\\\sqrt[3]{v^{12} } =v^4\\\sqrt[3]{z^6} =z^2[/tex]
Thus cube root of given expression = product of these four
= [tex]7x^3v^4z^2[/tex]
Option a is right
