Answer 1

Răspuns:

A) e = 3.

B) e=129

C)e=420

D)e=59

E)e=290

F)e=389

G)e=214

Explicație pas cu pas:

(2×3×4)+(25-16=

(6×4)+(25-16)=

24+9=33

(5×6×4)+(96-77)=

(30×4)+19=

120+19=129

(8×6×7)+(56+67)=

(42×7)+126=

294+126=420

(93-64)+(2×3×5)=

29+(6×5)=

29+30=59

(87+98)+(7×3×5)=

185+(21×5)=

185+105=290

(125-96)+(9×8×5)=

29+(72×5)=

29+360=389

(6×3×7)+(252-164)=

(18×7)+88=

126+88=214
