Solutions:

1.(12/17) ร (25/100) ร 1020 = 120 + ?
=> 180 = 120 + ?
=> ? = 180 โ 120 = 60

2.3942 = ? + 1203
=> ? = 3942 โ 1203 = 2739

3.[(25 ร 26)/13] โ 9
= ? โ 16
=> 41 = ? โ 16
=> ? = 41 + 16 = 57

4.โ(270 + 150 + 21) = ?2
=> โ441 = ?2 => ?2= 21
=> ? = โ21

5.72 ร (72) = 7? ร 73
=> [(72 ร 74) / 73] = 7? => 73 => 7? => ? = 3

6.[(420 ร 36) / 100] โ [(350 ร 56) / 100]
= ? โ 94
=> 151.2 โ 196 = ? โ 94
=> ? = 151.2 + 94 โ 196 = 49.2

7.? = 540 ร (75/100) ร (7/5) ร (2/3) = 378

8.(โ32)3 ร (โ34)5 รท (32)2= 3?
=> 33 ร 32ร5 รท 36= 3?
=> 33 + 10 -6 = 3?
=> 37 = 3?
=> ? = 7

9.? = 36 ร 15 โ [(56ร784)/112]
= 540 โ 392 = 148

10.28.314 โ 31.427 + 113.928
= ? + 29.114
