Question

Aflati patrimea numărului a: [a:2-(128:4+9×3)]-17×13=301

Answer 1

(a:2-(128:4+9*3))-17*13=301
(a/2-(32+27))-221=301
(a/2-59)-221=301
a/2-59-221=301
a/2-280=301
a-560=602
a=602+560
a=1162
patrimea:  1162:4 = 290,5 

Answer 2

[a:2-(128:4+9×3)]-17×13=301
[a/2-(32+27)]-221=301
a/2-59-221=301
a/2-280=301
a-560=602
a=602+560
a=1162

a:4=1162:4=290,5
