Simplify:
`13/11 xx (-14)/5 + 13/11 xx (-7)/5 + (-13)/11 xx 34/5`
उत्तर
Given, `13/11 xx (-14)/5 + 13/11 xx (-7)/5 + (-13)/11 xx 34/5`
= `(13 xx (-14))/(11 xx 5) + (13 xx (-7))/(11 xx 5) + ((-13) xx 34)/(11 xx 5)`
= `(-182)/55 + ((-91))/55 + ((-442))/55`
= `(-182 - 91 - 442)/55` ......[Taking LCM]
= `(-715)/55`
= –13
