Mult succes în continuare!

Answer 2

Răspuns:

a) (4+3-5) la puterea a 2= (7-5) la puterea 2= 2 la puterea 2= 4

b) 5×9+4×9-2×9=45+36-18=81-18=63

c) 33-27+16-4×5= 6+16-20=22-20=2

d) 353+221=574

e) 3605+8470-11725= 12075-11725=350

f) 103+228-32= 331-32=299

g) 4036081-4034072-2008= 2009-2008=1

h) (3×8-3×4+25-1)÷36= (24-12+24)÷36= (12+24)÷36= 26÷36= 0,72

i) [144÷144+3×(27×2-6×8)+8]÷9+9= [1+3×(54-48)+8]÷9+9= [1+3×6+8]÷9+9= [1+18+8]÷9+9= [19+8]÷9+9= 27÷9+9= 3+9= 12

j) 4×[(2×12÷4+25×2+69+3)÷32]-3= 4×[(24÷4+50+69+3)÷32]-3= 4×[(6+50+ 69+3) ÷32]-3=

4×[(56+69+3)÷32]-3

4× [(125+3)÷32]-3

4×[128÷32]-3

4×42,6-3= 170,4-3=167,4

k) [(1+(2) la puterea 15-13)+ (7) la puterea 2018-2015)) - (1+343-4)] la puterea 10=

=[(1 + 2²+7³)– (344-4)]¹⁰

=[(1+4+343) – 340]¹⁰

=[(5+343) – 340] ¹⁰

=[348-340]¹⁰

=8¹⁰

l)2⁹–2³×²=2⁹-2⁶=512–64=448
