Question

if x = root 7 / 5 and 5/x = p root 7, then find the value of p ?

Answer 1

$$\begin{gathered} \mathrm{Given},\mathrm{x}=\frac{\sqrt{7}}{5} \\ \mathrm{Now}, \\ \frac{5}{\mathrm{x}}=\mathrm{p}\sqrt{7} \\ \Rightarrow \frac{5}{\frac{\sqrt{7}}{5}}=\mathrm{p}\sqrt{7} \\ \Rightarrow \frac{25}{\sqrt{7}}=\mathrm{p}\sqrt{7} \\ \Rightarrow \mathbf{p}\mathbf{=}\frac{\mathbf{25}}{\mathbf{7}} \end{gathered}$$
