Giúp với!

Answer 1

\(\dfrac{97531\times36-24680}{97531\times35+72851}\)

\(=\dfrac{97531\times35+97531-24680}{97531\times34+72851}\)

\(=\dfrac{97531\times34+72851}{97531\times34+72851}\)

=1

Answer 2

`(97531 xx 36-24680)/(97531 xx 35+72851)`

`= (97531 xx (35 + 1) -24680)/(97531 xx 35+72851)`

`= (97531 xx 35 + 97531 -24680)/(97531 xx 35+72851)`

`= (97531 xx 35 +72851)/(97531 xx 35+72851)`

`= 1`
