Question

plz help me friends I am in big trouble so plz find out Q no 6.​

Answer 1

a

${3}^{27} \div {3}^{14} = {3}^{2x} \\{ 3}^{27 - 14} = {3}^{2x} \\ {3}^{13} = {3}^{2x} \\ 2x = 13 \\ x = 6.5$

b

Step-by-step explanation:

${( \frac{6}{7}) }^{ - 4} \times { (\frac{6}{7}) }^{13} = {( \frac{6}{7})}^{3x} \\ { (\frac{6}{7}) }^{ - 4 + 13} = {( \frac{6}{7}) }^{3x} \\ 3x = 9 \\ x = 3$

Answer 2

$a) {3}^{27} \div {3}^{14} = {3}^{2x} \\ x = 6.5 \\ \\ \\ b) {( \frac{6}{7} )}^{ - 4} \times {( \frac{6}{7} )}^{13} = { (\frac{6}{7} )}^{3x} \\ x = 3$
