Question

5² . 2³ - 12 . 5 + 170 : 17 - 8

Answer 1

\(=25\cdot8-60+10-8=200-50-8=142\)

Answer 2

\(=25.8-12.5+170:17-8=200-60+10-8=140+10-8=150-8=142\)

Answer 3

Answer 4

  5² . 2³ - 12 . 5 + 170 : 17 - 8

= (25 . 8) - (12 . 5) + (170 : 17) - 8

= 200 - 60 + 10 - 8

= 140 + 10 - 8

= 150 - 8

= 142
