Question

va rog frumos exercițiul 11

Answer 1

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•69
=7•(7+7•11)+98-207
=7•(7+77)+98-207
=7•84+98-207
=588+98-207
=485
b)(9+3^4:9^2):10+81•82:41:3^3-(2013^2014)^0
=[9+3^4:(3^2)^2]:10+161:27-1
=(9+3^4:3^4):10+6-1
=10:10+5
=1+5
=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
=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
=68940
