25 • [ 13 • 72 : ( 1 + 23 : x ) - 36 ] - 37 = 38

25 • [ 13 • 72 : ( 1 + 23 : x ) - 36 ] = 38 + 37 = 75

13 • 72 : ( 1 + 23 : x ) - 36 = 75 : 25 = 3

13 • 72 : ( 1 + 23 : x ) = 3 + 36 = 39

72 : ( 1 + 23 : x ) = 39 : 13 = 3

1 + 23 : x = 72 : 3 = 24

23 : x = 24 - 1 = 23

23 : x = 23

=> x = 23 : 23 = 1

x = 1

Explicație pas cu pas:

25•[13•72:(1+23:x)-36]-37=38

25•[13•72:(1+23:x)-36] = 37 + 38 = 75

13•72:(1+23:x)-36 = 75 : 25 = 3

13•72:(1+23:x) = 36 + 3 = 39

72:(1+23:x) = 39 : 13 = 3

1+23:x = 72 : 3 = 24

23 : x = 24 - 1 = 23

x = 23 : 23 = 1
