A)

The expression is (3•y)•z

Using associative property of multiplication: (a•b)•c=a•(b•c) , we get,

(3•y)•z  = 3•(y•z)

Equivalent expression is 3•(y•z)

 

B)

The expression is x +(y + 21)

Using associative property of addition: (a+b)+c=a+(b+c) , we get,

x +(y + 21) = (x + y) +21

Equivalent expression is (x + y) +21
