Answer 1

G)900-[(648:4+350:5):2]x3

=900-[(162+350:5):2]×3

=900-[162+70)]×3

=900-(232:2)×3

=900-116×3

=900-348

≈552

h)95-[25:(45:9)+(36:9×3-6)]

=95-[25:5+(4x3-6)]

=95-[25:5+(12-6)]

=95-(25:5+6)

=95-(5+6)

=95-11

=84

i)[84+(630:6×4)-(312:8×2)-298]:(8×864:108)

=[84+(105×4)-(312:8×2)-298]:(8×864:108)

=[84+420-(39×2)-298]:8×864:108

=(84+420-78-298):(8×864:108)

=(84+420-78-298):(8×8)

=(84+420-78-298:16)

=(504-78-298:16)

=(426-298:16)

=(128:16)

=8

j)314-2×[(16+15)×(83-79)]

=314-2×[31×(83-79)]

=314-2×(31×4)

=314-2×124

=314-248

=66

celalate cred ca nu le-ai transcris bine sau poate eu nu le-am înțeles!
