Question

va rog mult exercitiul de mai jos

Answer 1

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
