10 x [6^2 x 2^2 ÷ (3^2 x 2^2)] + 3^2 - 2^2 - (5 x 10 - 7^2)^0 - 10^3 ÷ 5^3
10 x [6^2 x 2^2 ÷ (3^2 x 2^2)] + 3^2 - 2^2 - (5 x 10 - 7^2)^0 - 10^3 ÷ 5^3
$10[6^2·2^2 : (3^2·2^2)]+3^2-2^2-(5·10-7^2)^0-10^3 : 5^3$ =
= $10[(6·2)^2 : (3·2)^2]+9-4-1-(10 : 5)^3$ =
= $10[(12)^2 : (6)^2]+4-(2)^3$ =
= $10[(12 : 6)^2]+4-8$ =
= $10·2^2+4-8$ =
= $10·4+4-8$ =
= $40+4-8$ =
= $36$
