Question
$\Big(\frac{13}{14}\Big)^{5}\div(\ )^{2}=\Big(\frac{13}{14}\Big)^{3}$

Answer

$\Big(\frac{13}{14}\Big)^{5}\div(\text{x})^{2}=\Big(\frac{13}{14}\Big)^{3}$

Solution:

Let $\Big(\frac{13}{14}\Big)^{5}\div(\text{x})^{2}=\Big(\frac{13}{14}\Big)^{3}$

$\therefore(\text{x})^{2}=\frac{\Big(\frac{13}{14}^{5}\Big)}{\Big(\frac{13}{14}\Big)^{3}}$

$\therefore(\text{x})^{2}=\Big(\frac{13}{14}\Big)^{5-3}$ $\big[\because\frac{\text{a}^{\text{m}}}{\text{a}^{\text{n}}}=\text{a}^{\text{m-n}}\big]$

$\therefore(\text{x})^{2}=\Big(\frac{13}{14}\Big)^{2}$

Since, powers are same.

$\therefore\text{x}=\frac{13}{14}$

Hence, $\Big(\frac{13}{14}\Big)^{5}\div(\text{x})^{2}=\Big(\frac{13}{14}\Big)^{3}$
