Question : The value of $0. \overline{57}-0.4 \overline{32}+0.3 \overline{5}$ is:
Option 1: $0.4 \overline{98}$
Option 2: $0.4 \overline{94}$
Option 3: $0. \overline{498}$
Option 4: $0. \overline{495}$
Correct Answer: $0.4 \overline{98}$
Solution : $0. \overline{57}-0.4 \overline{32}+0.3 \overline{5}$ can be written as $=\frac{57}{99} - \frac{428}{990} + \frac{32}{90}$ $=\frac{(570 - 428 + 352)}{990}$ $=\frac{494}{990}$ [Converting into expression: 4 will be added with unit digit as the denominator having '0' in it) Value of the given Expression = $0.4 \overline{98}$
Question : If $\left(x - \frac{1}{x}\right) = 2 \sqrt{2}$, what is the value of $\left(\mathrm{x}^6 + \frac{1}{\mathrm{x}^6}\right)$?
Option 1: 1030
Option 2: 960
Option 3: 1000
Option 4: 970
Correct Answer: 970
Solution : Given: $\left(x - \frac{1}{x}\right) = 2 \sqrt{2}$ We know, $(x - \frac{1}{x})^{3} = x^{3} - \frac{1}{x^3} - 3×x×\frac{1}{x}(x - \frac{1}{x})$ $⇒(x - \frac{1}{x})^{3} = x^{3} - \frac{1}{x^3} - 3 \times 2\sqrt{2}$ $⇒(2\sqrt{2})^{3} = x^{3} - \frac{1}{x^3} -6\sqrt{2}$ $⇒x^{3} - \frac{1}{x^3} = 22\sqrt{2}$ $⇒(x^{3} - \frac{1}{x^3})^{2}
