Question

Correct option is

C

9−4​;713​;115​;14−11​

The additive inverse of 94​ is −94​=9−4​

The additive inverse of 7−13​ is −(7−13​​)=−(−713​​)=713​

We have, −115​=11−5​
The additive inverse of 11−5​ is −(11−5​​)=−(−115​​)=115​

We have, −14−11​=1411​
The additive inverse of 1411​ is −(1411​​) =14−11​
