Question

Comparati a cu b+c unde:
a=10^3:{123+34:[(2×3^2)^2:18-2002^0×1^2003]}
b=(3^2^2003^0+2^3^1^2003+2^3×5^3:10^2):3^3
c=[3^2003:(3^2)1001+(5^3)^2:5^2^2]:2^2

Semnul ^ inseamna la puterea

Answer 1

a=10^3:{123+34:[(2×3^2)^2:18-2002^0×1^2003]}

a=1000:{123+34:[(2*9)^2:18-1]}

a=1000:[123+34:(18^2:18-1)]

a=1000:[123+34:17]

a=1000:(123+2)

a=1000:125

a=8

b=(3^2^2003^0+2^3^1^2003+2^3×5^3:10^2):3^3

b=(1+2^6009+10^3:10^2):3^3

b=(1+2^6009+10):3^3

b=(11+2^6009):3^3

c=[3^2003:(3^2)1001+(5^3)^2:5^2^2]:2^2

c=[3^2003:3^2002+5^6:5^4]:2^2

c=(3+5^2):2^2

c=(3+25):4

c=28:4=7

a=8

b=(11+2^6009):3^3

c=7

? inseamna comparat.

a?b+c

8?7+(11+2^6009):3^3 scadem 7

1?(11+2^6009):3^3 inmultim cu 3^3

3^3?(11+2^6009)

27?11+2^6009

16?2^6009

2^4?2^6009

4<6009
