Answer 1

1.a=200,43
b=139,52
a+b=339,95
2.17,85+(107,5-87,557)=17,85+19,943=37,793
3.a)3,125+15+82,3-17,32=83,105
b)13,7-1,05+21,31=33,96
a-b=83,105-33,96=49,145
4.a)x=24,43-8,938
x=15,492
24,43-15,492=8,938
b)x=132,57-7,28
x=125,29
7,28+125,29=132,57
c)x=37,5=132,04
x=132,04+37,5
x=169,54
169,54-37,5=132,04
d)23,5+4=27,5
27,5-4x
x=23,5
5.{[1,43)²] la puterea 17}³=1,43 la puterea x-1
1,43 la puterea 102=1,43 la puterea x-1
x-1=102
x=102+1=103
