Answer 2

2 pag.1
x=(7²*2-34):2³
x=(49*2-34):2³
x=(98-34):2³
x=64:8
x=8

y=(5³*2+20):3³=
y=(125*2+20):3³=
y=(250+20):3³=
y=270:27
y=10

mₐ=(8+10):2=18:2=9


2 pag.2
x=(2³-3⁰)³:7²
x=(8-1)³:7²
x=7³:7²
x=7³⁻²
x=7

y=(3²+2)³:11
y=(9+3)³:11
y=12³:11
y=1728:11
y=157

mₐ=(7+157):2=164:2=82

4 pag.2
(1+2+3+4+....+99):87
99*100:2= 9900:2= 4950
4950:87=4872 rest 78

5 pag.2
25x+46≤146
25x≤146-46
25x≤100
    x≤100:25
    x≤4

Solutia este 4.
