Associative Property of Multiplication:
\The way in which numbers are grouped when multiplied does not change the
\product. For any numbers a, b and c: ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=fca61658b37c4cf8c1593ce695acbefc.png\")
.
According to associative property of multiplication, the statement can be written as
\![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=fbdf7ee3f8c11bee461d09f937fd6bed.png\")

![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=fbfbb717bb9d4fb42b8f8ebead8012c9.png\")
(Multiply: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8bf9b50d7bbbfc7473950587ed05d2d1.png\")
) ![\"\"](\"/userfiles/image/steps_images/solution.JPG\")
The simplified expression is 75b.
