Question

a)
11 4 ori { 256 : 16 3 ori [ 175 : 25 - 4 ori ( 33- 4 ori 8 ]} 19 ori x = 2011

b){201-66:3 + 5 ori (3 la puterea a 2 a - 2 la puterea a 3 a) ] : x = 4

c)23 + 24 +25 + ... + 122 - 7 ori 11 = x+ 23 ori47 - 23 ori 46

d) (2000-2 ori 10) ori (2000-2 ori 10 la puterea a 2a) ori (2000-2 ori 10 la puterea a 3 a) + 4 ori x = 576

Answer 1

a) 114*{256:163*[175:25-4*(33-4*8)]}19*x=2011
114*[256:163*(175:25-4*1)]19*x=2011
114*(256:163*3)19*x=2011
114*265:489*19*x=2011
30210:9291*x=2011
x=2011-30210:9291
x=2011-3,25
x=2007,75.
