Simplify:(7/6power 20÷(7/6)power 18​

Answer 1

$Given \: \Big( \frac{7}{6}\Big)^{20} \div \Big( \frac{7}{6}\Big)^{18}$

$= \Big( \frac{7}{6}\Big)^{20-18}$

/* By Exponential Law */

$\boxed{ \pink{ \frac{x^{m}}{x^{n}} = x^{m-n}}}$

$= \Big( \frac{7}{6}\Big)^{2}$

$= \frac{7^{2}}{6^{2}}$

$= \frac{49}{36}$

Therefore.,

$\red{ \Big( \frac{7}{6}\Big)^{20} \div \Big( \frac{7}{6}\Big)^{18}}$

$\green {= \frac{49}{36} }$
