Answer :
To solve the equation [tex]\(\sqrt[12]{7 x^9 + 4 x^2} + 4 = 2\)[/tex], we need to isolate the term inside the radical. Here are the steps to solve it:
1. Subtract 4 from both sides:
[tex]\[
\sqrt[12]{7 x^9 + 4 x^2} + 4 - 4 = 2 - 4
\][/tex]
This simplifies to:
[tex]\[
\sqrt[12]{7 x^9 + 4 x^2} = -2
\][/tex]
Hence, the first step is:
Option 3: Subtract 4 from both sides of the equation.
So the correct option is number 3.
