Tính nhanh ạ

Answer 1

\(I=16\times102+24\times98+48\times17\)

\(I=1632+2352+816\)

\(I=4800\)

Answer 2

I = 16 x 102 + 24 x 98 + 48 x 17

I=1632 +2352+816

I=3984+816

I=4800

Answer 3

`16 xx 102 + 24 xx 98 + 48 xx 17`

`= 16 xx 3 xx 34 + 24 xx 2 xx 49 + 48 xx 17`

`= 48 xx 34 + 48 xx 49 + 48 xx 17`

`= 48 xx (34 + 49 + 17)`

`= 48 xx 100`

`= 4800`

 

Answer 4

16 x 102 + 24 x 98 + 48 x 17

= 34 x 48 + 49 x 48 + 48 x 17

= 48 x (34 + 49 + 17)

 = 48 x 100 

= 4800
