Đáp án:
Giải thích các bước giải:
`47568 : 4 : 2 xx 135
= `11892 : 2 xx 135`
= `5946 xx 135`
= `802710`
________________
`( 427 xx 54 + 427 xx 45 ) : 5`
= `427 xx ( 54 + 46 ) : 5`
= `( 427 xx 100 ) : 5`
= `42700 : 5`
= `8540`
_______________
`2005 - ( 175 : 5 - 34 ) xx 92`
= `2005 - ( 35 - 34 ) xx 92`
= `2005 - 92`
= `1913`
_____________
`( 4578 + 3689 ) : 7 + 1789`
= `8267 : 7 + 1789`
= `1181 + 1789`
= `2970`
_____________
`36576 : ( 4 xx 2 ) - 3708`
= `36576 : 8 - 3708`
= `4572 - 3708`
= `864`
____________
`81756 - ( 456 xx 54 ) : 9`
= `81756 - 24624 : 9`
= `81756 - 2736`
= `79020`
