Answer 1

Răspuns:

a)7·{7+7·[7^6-(7^2)^3+11 ]}+2·7^2-3 ·23=

7·[7+7·(7^6-7^6+11)]+2·49-3·23=

7·[7+7·(0+11)]+98-69=

7·(7+7·11)+98-69=

7·(7+77)+98-69=

7·84+98-69=

588+98-69=

686-69=617

b)(9+3^4:9^2):10+81·82:41:3^3-(2013^2014)^0=

(9+3^4:(3^2)^2):10+6642:41:27-1=

(9+3^4:3^4):10+162:27-1=

(9+1):10+6-1=

10:10+6-1=

1+6-1=

7-1=6

c)18176:71-3·(29·24-23·30)+11^7:11^5=

256-3·(696-690)+11^2=

256-3·6+121=

256-18+121=

238+121=359

d)(84084:42+13):403+9·[85085:11-3·(73·16-1143)]=

(2002+13):403+9·[7735-3·(1168-1143)]=

2015:403+9·(7735-3·25)=

5+9·(7735-75)=

5+9·7660=

5+68940=68945
