Question

Efectuati:f)2^3+[(2^3)^7-(2^7)^3+3x3^4-81]:{3^2x[301-10x(24+2^2012:2^20011x3)]}.Va rog e foarte urgent dau coroana

Answer 1

2^3 + [(2^3)^7 - (2^7)^3 + 3 x 3^4 - 81] : {3^2x[301 - 10 x (24 + 2^2012 : 2^2011x3)]}=
= 2^3 + (2^21 - 2^21 + 3^5 - 3^4) : {3^2 x [301 - 10 x (24 + 2^1 x 3)] =
= 8 + (0 + 243 - 81) : {9 x [301 - 10 x (24 + 6)] = 
= 8 + 162 : [9 x (301 - 10 x 30) =
= 8 + 162 : 9 = 
= 8 + 18 =
= 26
