Step-by-step explanation:

Answer is given

In these 2 pic above 3 questions solutions is written

Answer 2

Solution - 1

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

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

$\{ \sf 3 ^{ 3} \: - \: 2 ^{3} \: \} \div \: 4 ^{3}$

$\{ \sf \small 3 \times 3 \: \times \: 3 \: - 2 \: \times 2 \times 2 \} \div \: 4 \times 4 \times 4 \times 4$

$\{ \sf \: 21 \: - \: 8 \: \} \: \div \: 64$

$\sf 19 \: \: \div \: 64$

$\sf \blue{So, \: Our \: answer \: is \: \: \dfrac{19}{64} }$

Solution - 2

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

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

$\sf \bigg \{ \dfrac{3 - 16}{4} \: \bigg\} ^{ - 1}$

$\sf \bigg \{ \dfrac{ - 13}{4} \: \bigg \}^{ - 1} \: \: = \: \: \dfrac{ -4}{13} \:$

$\sf \blue{So, \: Our \: answer \: is \: \: - \dfrac { 4}{13} }$

Solution - 3

$\large [ (5 ^{ - 1} \: \times \: 3^{ - 1} )] \: \div \: 6 ^{ - 1} ]$

$\bigg [ \bigg( \dfrac{1}{5} \: \times \: \dfrac{1}{3} \bigg)\bigg]^{ - 1} \: \div \: \dfrac{1}{6} \ \bigg]$

$\sf \: \bigg[ \dfrac{1}{15} ^{ - 1} \: \div \: \dfrac{1}{6} \: \bigg]$

$\sf \: \bigg[ \dfrac{15}{1} ^{ } \: \div \: \dfrac{1}{6} \: \bigg]$

$\sf \: \dfrac{15}{1} ^{ } \: \times \: \dfrac{6}{1} \: = \: \dfrac{90}{1}$

$\sf \blue{So, \: Our \: answer \: is \: \: \dfrac {9}{1} }$
