chuc ban luon hoc tot! ma ban co the ket ban voi min dc ko?

Tính nhanh mà

2448 : [119 - (23 - 6)]

2448 : [ 119 - ( 23 - 6 )] 

= 2448 : [ 119 - 17 ]

= 2448 : 102

= 24

2448 : [119 − (23 − 6)]

= 2448 : (119 – 17)

= 2448 : 102 = 24

Tính:

\(2448:\left[119-\left(23-6\right)\right]\)

\(=2448:\left[119-17\right]\)

\(=2448:102\)

\(=24\)
