Question

1.

a. 17.93+116.83+17.23

Answer 1

\(17.93+116.83+17.23.\)

\(=17\left(93+23\right)+116.83.\)

\(=17.116+116.83.\)

\(=116\left(17+83\right).\)

\(=116.100=11600.\)

Vậy.....

Answer 2

17 . 93 + 116 . 83 +17 . 23

= 17 . (93 + 23) + 116 . 83

= 17 . 116 + 116 . 83

= 116 . (17 + 83)

= 116 . 100

= 11600

Answer 3

Answer 4

17 . 93 + 116 . 83 +17 . 23

= 17 . (93 + 23) + 116 . 83

= 116 . (17 + 83)

= 116 . 100

= 11600

Answer 5
