Answer 1

x = 6

Step-by-step explanation:

${( \frac{12}{13} )}^{4} \times (\frac{13}{12} {)}^{ - 8} = ( \frac{12}{13} {)}^{2x} \\ \\ = > ( \frac{12}{13} {)}^{4} \times (\frac{12}{13} {)}^{8} = ( \frac{12}{13} {)}^{2x} \\ \\ = > {( \frac{12}{13} })^{4 + 8} = {( \frac{12}{ 13} })^{2x} \\ \\ = > ( \frac{12}{13} {)}^{12} = ( \frac{12}{13} {)}^{2x} \\ \\ = > 12 = 2x \\ \\ = > \frac{12}{2} = x \\ \\ = > 6 = x \\ \\ = > x = 6$

So,

the value of x = 6.

Rules we used or you will use later,

${x}^{m} \times {x}^{n} = {x}^{m + n} \\ {x}^{m} \div {x}^{n} = {x}^{m - n} \\ ( {x}^{m} {)}^{n} = {x}^{m \times n} \\ (\frac{x}{y} {)}^{ - m} =( \frac{y}{x} {)}^{m}$

hope it helps.
