1. The problem is to simplify the expression where the square root (racine) applies only to the first 6, not the entire term. 2. Let's assume the expression is something like $\sqrt{6} + 4$ or $\sqrt{6} \times 4$, where the square root applies only to 6. 3. The key rule is that the square root symbol $\sqrt{}$ applies only to the number or expression inside it. 4. For example, $\sqrt{6} + 4$ means take the square root of 6, then add 4. 5. If the expression is $\sqrt{6} \times 4$, then take the square root of 6 and multiply by 4. 6. Calculate $\sqrt{6} \approx 2.449$. 7. So, $\sqrt{6} + 4 \approx 2.449 + 4 = 6.449$. 8. Or, $\sqrt{6} \times 4 \approx 2.449 \times 4 = 9.796$. 9. Always be careful with the placement of the square root symbol to know exactly what it applies to. 10. If you provide the exact expression, I can help simplify it step-by-step.
