Question

Ex 3 punctul b c si d daca nu le puteti face oe toate trei faceti diar unul dau coroana si inima

Answer 1

b) 2^3 * 3^2 + 25^0*11^2 - 4^0 = 8*9 + 1*121-1 = 72 + 121 - 1 = 162

c) 1 + { 2 + [3*(4+5)-6+7*8]-0} = 1 + [ 2 + (3*9-6+56)-9] = 1 + [2 +(27-6+56)-9] =

1 + (2+77-9) = 1 + 70 = 71

d) 9*{[8+7*(6+5)]*4-3}+2 = 9*[(8+7*11)*4-3]+2 = 9*[(8+77)*4-3]+2 =

9*(85*4-3)+2 = 9*(340-3)+2 = 9*337+2 = 3033+2 = 3035
