Answer 1

Answer:

${( \frac{11}{12} )}^{ - } \: \div \: {( \frac{11}{12} )}^{ 22} = \frac{1}{{( \frac{11}{12} )}^{ 2}}$

=

${( \frac{11}{12} )}^{ - } \: \times \: {( \frac{12}{11} )}^{ 22} = \frac{1}{{( \frac{11}{12} )}^{ 2}}$

=

${( \frac{11}{12} )}^{ - } \: = \frac{1}{{( \frac{11}{12} )}^{ 2}} \div {( \frac{12}{11} )}^{ 22}$

=

${( \frac{11}{12} )}^{ - } \: = {{( \frac{12}{11} )}^{ 2}} \div {( \frac{12}{11} )}^{ 22}$

=

${( \frac{11}{12} )}^{ - } \: = {{( \frac{12}{11} )}^{ 2}} \times {( \frac{11}{12} )}^{ 22}$

=

${( \frac{11}{12} )}^{ - } \: = \frac{ {11}^{ 20} }{{12}^{20} }$

${( \frac{11}{12} )}^{ 20 } \: is \: the \: required \: answer$

Answer is 20.
