Question

34^2-3^2+{2018^0+2^3+7^1[5^3-2^2(10^3+3^2):x]}=2017*2018-2017^2

Answer 1

1.156-9+{1+8+7×[125-4(1.000+9):x]}=4.070.306-4.068.289
1.156-9+{1+8+7×[125-4×1.009:x]}=2.017
9+[1+8+7×{125-4.036:x]}=2.017-9
9+{1+8+7×[125-4.036:x]}=2.008
{1+8+7×[125-4.036:x]}=2.008-9
1 +8+7×[125-4.036]=1.999
8+7×[125-4.036]=1.999-1
8+7×[125-4.036]=1.998
7×[125-4.036]=1.998-8
7×[125-4.036]=1.990
[125-4.036]
