Question 2

$\LARGE{ \underline{ \tt{Required \: answer:}}}$

To Solve:

Solution:

$\large\rm{ \leadsto { (5)/(3) }^( - x). { (5)/(3) }^(2x) = \frac{5 {}^(3) }{3 {}^(3) } }$

$\large \rm{ \leadsto \frac{5 {}^(2x - x) }{ {3}^(2x - x) } } = \frac{5 {}^(3) }{ {3}^(3) }$

$\large \rm{ \leadsto \frac{5 {}^(x) }{ {3}^(x) } = \frac{5 {}^(3) }{ {3}^(3) } }$

$\large\rm{ \leadsto { \bigg( (5)/(3) \bigg) }^(x) = \bigg( (5)/(3) \bigg) ^(3) }$

Then,

The required value of x is 3.
