Question

Sa se efectueze :
1) { 10 la 2 - [(4+3 la 2 ) ori 5 - 10] } : (3 la 2 ori 5 ) =

Answer 1

{10²-[(4+3²)×5-10]}:(3²×5)=
={100-{(4+9)×5-10]}:(9×5)
=[100-(13×5-10)]:45
=[100-(65-10)]:45
=(100-55):45
=55:45
=1,(2)

Esti sigur ca ai scris corect?

Answer 2

100-{(4+9)×5-10]}:(9×5)
[100-(13×5-10)]:45 ..   9x5 = 45 
[100-(65-10)]:45
(100-55):45 facem mai intai din paranteza
45 : 45
= 1 ! . sper ca e bine .
