Answer 2

Simplify :

$\bigg( \dfrac{1}{2} \bigg)^{ - 2} \: + \: \bigg( \dfrac{1}{3} \bigg)^{ - 2} \: \bigg( \dfrac{1}{4} \bigg)^{ - 2}$

$\bigg( \dfrac{2}{1} \bigg)^{ 2} \: + \: \bigg( \dfrac{3}{1} \bigg)^{ 2} \: + \: \bigg( \dfrac{4}{1} \bigg)^{2}$

$\bf \: 2^{2} \: + \: 3^{2} \: + \: 4^{2}$

$\sf \underline{2 \times 2 }\: + \: \underline{3 \times 3} \: + \underline{4 \times 4}$

$\sf \longrightarrow \: 4 \: + \: 9 \: + \: 16 \:$

$\sf \purple {Hence \: answer \: is \: 29. }$
