Solve this problem :

${1}^{ - 2} + {2}^{ - 2} + {3 }^{ - 2 } \times {6}^{2}$

$\color {red} </p><p>\Large \underline {\underline {Answer \: :}}$

${1}^{ - 2} + {2}^{ - 2} + {3}^{ - 2} \times {6}^{2}$

$1 + ( \frac{1}{2}) {}^{ 2} + ( \frac{1}{3} ) {}^{2} \times 36$

$1 + \frac{1}{4} + \frac{1}{9} \times 36$

$1 + \frac{1}{4} + 4$

$5 + \frac{1}{4}$

$= \frac{21}{4}$

$\implies$ So, the answer is 21/4.
