By taking a common factor, we will see that the equivalent expression is:
[tex]12*\sqrt[3]{6c}[/tex]
Here we start with the expression:
[tex]5*\sqrt[3]{6c} + 7*\sqrt[3]{6c}[/tex]
Notice that if we define:
[tex]\sqrt[3]{6c} = u[/tex]
We can rewrite our expression as:
[tex]5u + 7u[/tex]
Now we can take the common factor u to write:
[tex](5 + 7)u = 12u[/tex]
Now if we replace u y the cubic root, we will get:
[tex]12*\sqrt[3]{6c}[/tex]
So the correct option is the third one.
