a) [6 • ( 14 - 2 • 6) : 3 ] ² = 14 - 2 • 6 = 2 • 6 = 12 : 3 = 4 .. 4² = 16
b) [ 15•( 17 -8 • 2)• 2-5•3] •2² - 10 = 782
1) 17 -8 • 2 = 1
2) 1 • 15 = 15
3) 5 • 3 = 15
4) 15 - 2 = 13
5) 15 • 13 = 195
6) 2² = 4
7) 198 • 4 = 792
8) 792 - 10 = 782
c) 5³- 3² + 7² + 11² = 286
a) 5³ = 152
b) 3² = 9
c) 7² = 49
d) 11² = 121
125 - 9 + 49 + 121 = 286
