Answer 1

3 (4x-1)

x=0
3 · (4 · 0 - 1) = 3 · (-1) = -3

x=3^3 = 27
3 (4 · 3^3 - 1) = 3 · (108 - 1) = 3 · 107 = 321

x=1/2
3 (4 · 1/2 - 1) = 3 (2-1) = 3

x=10
3 (40-1) = 3 · 39 = 117

x=3,5
3 (4 · 3,5 - 1) = 3 ( 14 - 1) = 3 · 13 = 39

x=1 (pe bune? :)) )
3 (4-1) = 3· 3 = 9

3 (4 · 3/4 - 1) = 3 (3-1) = 3 · 2 = 6

16x^2+10

x=8
16 · 8^2 + 10 | 16 = 2^4, 8 = 2^3
2^4 · (2^3)^2 + 10 = 2^4 · 2^6 + 10 = 2^10 + 10

x=0
16 · 0 + 10 = 10

x=3^3
16 · (3^3)^2 + 10 = 16 · 3^6 + 10 = 16 · 729 + 10 = 11.664 + 10 = 11.674

x=1/2
16 · (1/2)^2 + 10 = 16 · 1/4 + 10 = 4 + 10 = 14 (se simplifica 16 cu 4 prin 4, din 16 ramane 4 si din 4 ramane 1).

x=10
16 · 100 + 10 = 1600 + 10 = 1610

x=3,5
16 · (3,5)^2 + 10 = 16 · 12,25 + 10 = 196 + 10 = 206

x=1
16 · 1 + 10 = 16 + 10 = 26

x=3/4
16 · (3/4)^2 + 10 = 16 · 9/16 + 10 = 9 + 10 = 19 (se simplifica 16)
