Answer 1

Answer:

Step-by-step explanation:

Answer 2

Q 2

${( \frac{5}{3} )}^{2x} + {( \frac{5}{3}) }^{ - 14} = { \frac{5}{3} }^{2}$

${ (\frac{5}{3} )}^{2x - 14} = { (\frac{5}{2} )}^{2}$

Now

2x-14 = 2

2x = 16

X = 8

Q8...

${16}^{ - 2} = { {2}^{4} }^{ - 2} = {2}^{ - 8}$

${125}^{ - 4} = { {5}^{3} }^{ - 4} = {5}^{ - 12}$
