Question

efectuati:
207 x 9 - (19^2 + 3^2) : 74 + 2296 : 41

5 x 230 - 7 x (512 : 32 + 2^2) + 4687 : 43

[ 493 : 17 - (128 : 2^3 + 224 :8) : 22] : 27 - 1

sa clarific, ^ inseamna puterea
2^2 = 2 la puterea a doua

Answer 1

Răspuns:

207 × 9 - (361 +9) : 74 + 2296 :41 =1914

207 × 9 - 370 : 74 + 2296 : 41 =

1863 - 5 + 56 =

1858 + 56 = 1914

5×230-7×(16+4)+4687:43=1119

5×230-7×20+4687:43=

1150 - 140 + 109 =

1010 + 109 =1119

[ 493 :17-(128:8 +224:8):22]:27-1=0

[ 493:17 - ( 16 + 28) : 22] : 27 - 1 =

( 493 : 17 - 44 : 22 ) : 27 - 1 =

(29 - 2 ) : 27 - 1 =

27 :27 - 1 =

1 -1 = 0
