Answer 2

$\sf\huge\bold{Answer:}$

Given :

$= {3}^{ - 1} - {5}^{ - 1} - 1$

Solution :

$\fbox{Identity used:}$

$\implies \: a {}^{ - 1} = \frac{1}{a}$

Step 1 : Simplifying the term the above formula

$= \frac{1}{3} - \frac{1}{5} - 1$

Step 2 : Taking LCM

$= \frac{5 - 3 - 15}{15}$

Step 3 : Solving numerator

$= \frac{5 - 18}{15}$

Since,the larger number 18 is negative,on subtraction the resultant no. will also have negative sign.

$= \frac{ - 13}{ \: \: \: 15}$
