Question

6. Rezolvă, respectând ordinea operatiilor:
609 : 3 +852:4-695 : 5 =
170 x 10 : 17-( 120-45 ) x 2:5 =
383 + ( 1 000 - 502 ): 6 =
[ 472 +51 x 4-( 480 : 4 + 32 x 5 )] x 1 000 =
3 000 -5x [ 41 + ( 84 - 8x8:4):2] =​

Answer 1

Răspuns:

609:3+852:4-695:5=203+213-139=416-139=272

170×10:17-(120-45)×2:5=1700:17-75×2:5=100-150:5=100-30=70

383+(1000-502):6=383+498:6=383+83=466

[472+51×4-(480:4+32×5)]×1000=[472+204-(120+160)]×1000

=(676-280)×1000=396×1000=396000

3000-5×[41+(84-8×8:4):2]=3000-5×[41+(84-64:4):2=

3000-5×[41+(84-16):2]=3000-5×(41+68:2)=3000-5×(41+34)=

3000-5×75=3000-375=2625
