Va rog ajutati-ma la urmatoarele exercitii dau 20 puncte :
a) (17 + 17 x 17) : (17 x 18) + (215 +215 x 215) : (215x 216);
b) [( X-1): 100+90]:10 - 10=0
c) 9- (25 - 16) : 3= [18-3 x(9-9)] : x;
d) [(x + 270:3) x 5+100] :600=1;
e) {2x(x+8) x 3+4 x ( x+8)] : 4 =25

Cine raspunde corect ii dau coronita :>

Answer 1

a) (17+17×17):(17×18)+(215+215×215):(215×216)= (34×17):306+(430×215):46,440=578:306+92,450:46,440=1.8888888889+1.9907407407=3.8796296296
