dau coroană cine ma ajuta​

Answer 1

Voi scrie puterea cu simbolul ^

a) [(5^(20 + 5)):5^22 - (5^(2-1))]:2^3= (5^25 : 5^22 - 5^1) : 2^3 = (5^(25-22) - 5^1):2^3= (5^3 - 5^1):2^3= (125-5):8= 120:8 = 15

b) [(7^(11+23)):7^33 + 1]:8= (7^34 : 7^33 + 1):8= = (7^(34-33)+1):8= (7^1 + 1):8= (7+1):8= 8:8=1

c) [8+(2^(7+8+23)^2 : 2^70]:9= [8+(2^38)^2 : 2^70]:9= [8+ 2^(38•2) : 2^70]:9= [8+ 2^76 : 2^70] : 9= [8+ 2^(76-70)]:9= [8+ 2^6]:9= (8+64):9= 72:9= 8

d) [100-(6^(30+21)^5 : 6^253]:32= [100-(6^51)^5 : 6^253] : 32 = [100-(6^(51•5) : 6^253]:32= [100- 6^255 - 6^253] :32= [100- 6^(255-253)]:32= [100- 6^2]:32= (100-36):32= 64:32= 2
