Answer 1

Step-by-step explanation:

${( {2}^{ - 1} + {3}^{ - 1} })^{ - 2}$

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

${( \frac{3 + 2}{6} })^{ - 2}$

${( \frac{5}{6} )}^{ - 2}$

${( \frac{6}{5} })^{2}$

$( \frac{36}{25} )$

Answer 2

Answer:

${( {2}^{ - 1} + {3}^{ - 1} )}^{ - 2} \\ = {( \frac{1}{2} + \frac{1}{3} )}^{ - 2} \\ \\ = {( \frac{3 + 2}{6} )}^{ - 2} \\ \\ = {( \frac{5}{6} )}^{ - 2} \\ \\ = {( \frac{6}{5} )}^{2} \\ \\ = \frac{36}{25} \\ = 1.44$
