Answer 1

Answer:

To get answer as 1728, the power should be - 3 instead of -2, otherwise answer is 144.

Check both the answers

${( {4}^{ - 1} - {6}^{ - 1} )}^{ - 2} \\ = {( \frac{1}{4} - \frac{1}{6}) }^{ - 2} \\ = {( \frac{3 - 2}{12} )}^{ - 2} \\ = {( \frac{1}{12} )}^{ - 2} \\ = {12}^{2} \\ = 144$

${( {4}^{ - 1} - {6}^{ - 1} )}^{ - 3} \\ = {( \frac{1}{4} - \frac{1}{6}) }^{ - 3} \\ = {( \frac{3 - 2}{12} )}^{ - 3} \\ = {( \frac{1}{12} )}^{ - 3} \\ = {12}^{3} \\ = 1728$
