Va rogg multtt e urgentt!!!

Answer 1

7*{7+7*[7^6-7^6+11]}+2*7^2-69=
7*(7+7*11)+2*49-69=
7*(7+77)+98-69=
7*84+29=
588+29=617

b. 9^2=(3^2)^2=3^(2*2)=3^4
(9+3^4:3^4):10+81*2:27-2013^(2014*0)=
10:10+6-1=6

c.256-3*(696-690)+11^(7-5)=
256-3*6+11^2=256-18+121=359

d. (2002+13):403+9*[7735-3*(1168-1143)]=
5+9*(7735-3*25)=5+9*(7735-75)=5+9*7660=5+68940=68945
