Answer 4

C1: 147\(\times\)14-147\(\times\)4

=> 147(14-4)

=> 140 . 10

=> 1470   ( chú ý dấu . là dấu nhân)

C2: 147. 14-147.4

=> 2058- 588

=> 1470

Answer 5

C1:                                                                            C2:

\(147.14-147.4\)                                                \(147.14-147.4\)

\(=2058-588\)                                                   \(=147.\left(14-4\right)\)

\(=1470\)                                                                  \(=147.10\)

                                                                                       \(=1470\)
