a) 135 900 – (200 900 – 80 050) = 135 900 – 120 850 = 15 050
6 000 – 4 500 + 14 000 = 15 500
Vậy 135 900 – (200 900 – 80 050) < 6 000 – 4 500 + 14 000
b) 34 785 + 20 300 – 2 785 = 55 085 – 2 785 = 52 300
20 350 + 18 127 + 8 450 = 38 477 + 8 450 = 46 927
Vậy 34 785 + 20 300 – 2 785 > 20 350 + 18 127 + 8 450

a: \(17464-17464:74-74\cdot158\)
\(=17464\cdot\left(1-\dfrac{1}{74}\right)-74\cdot158\)
\(=17464\cdot\dfrac{73}{74}-74\cdot158\)
\(=5536\)
10 tháng 12 2021
17464 - 17464 : 74 - 74 x 158
= 158 x ( 17464 - 17464 ) : ( 74 - 74 )
= 158 x 0 : 0
= 0 x 0
= 0
