Answer 1

Answer:

x = 3

Option (b) is the correct answer.

Step-by-step explanation:

Given that, $(\frac{6}{5} )^x (\frac{5}{6} )^{2x} = \frac{125}{216}$

$=>(\frac{1}{\frac{6}{5} } )^{-x} (\frac{5}{6} )^{2x} = \frac{125}{216}$  [∵ $\frac{1}{a^{(-m)}} = a^m$]

$=>(\frac{5}{6} )^{-x} (\frac{5}{6} )^{2x} = \frac{5^3}{6^3}$

$=>(\frac{5}{6} )^{2x-x} = (\frac{5}{6})^3$  [∵ $a^m.a^n = a^{(m+n)}$ and $\frac{a^m}{b^m} = (\frac{a}{b} )^m$]

∴ 2x - x = 3

∴ x = 3

Option (b) is the correct answer.
