Answer 2

$\mathbb{REVIEW \: \: SOME \: \: FORMULA:- }$

$\bold{ {x}^{0} = 1} \\ \\ \bold{{x}^{1} \times {x}^{1} = {x}^{2} }$

$\mathbb{\bold{TOPIC:- EXPONENT \: AND\: POWER }}$



$\mathbb{\huge{QUESTION:- }}$




$\implies\bold{ {(0.2)}^{(2x - 1)} = 1}$



$\mathbb{METHOD \: \: OF \: \: SOLUTION - }$



$\implies\bold{ {(0.2)}^{(2x - 1)} = 1} \\ \\ \\ \implies \bold{ {(0.2)}^{(2x - 1)} = {0.2}^{0}} \\ \\ \\ \implies \bold{ { \cancel{0.2}}^{(2x - 1)}= { \cancel{0.2}}^{0}} \\ \\ \\ \\ \implies \bold{2x - 1 = 0} \\ \\ \\ \implies \bold{2x = 1} \\ \\ \\ \implies \bold{x = \frac{1}{2}}$

================================

$\mathbb{METHOD \: \: OF \: \: SOLUTION - }$



$\mathbb{\huge{QUESTION:- }}$



$\bold{ {11}^{3x - 1} = 121}$



$\mathbb{METHOD \: \: OF \: \: SOLUTION - }$



$\implies\bold{ {11}^{3x - 1} = 121} \\ \\ \\ \implies \bold{ {11}^{3x - 1} = {11}^{2}} \\ \\ \implies \bold{ { \cancel{11}}}^{3x - 1} = { \cancel{11}}^{2} \\ \\ \\ \implies \bold{3x - 1 = 2} \\ \\ \implies\bold{3x = 2 + 1} \\ \\ \\ \\ \implies\bold{3x = 3} \\ \\ \\ \implies \bold{x = \frac{3}{3} = 1}$
