1. The problem is to understand and analyze the formula $P=\frac{\sqrt{2t}}{g}$. 2. This formula expresses $P$ as the ratio of the square root of $2t$ to $g$. 3. Important rules: - The square root function $\sqrt{x}$ means the positive root of $x$. - Division by $g$ means $P$ is inversely proportional to $g$. 4. To simplify or evaluate, you can substitute values for $t$ and $g$. 5. For example, if $t=8$ and $g=4$, then: $$P=\frac{\sqrt{2\times8}}{4}=\frac{\sqrt{16}}{4}=\frac{4}{4}=1$$ 6. This formula might be used in physics or engineering contexts where $t$ and $g$ represent time and acceleration due to gravity respectively. 7. Always ensure $t\geq0$ because the square root of a negative number is not real. Final answer: $P=\frac{\sqrt{2t}}{g}$
