Expert verified

The value of the expression is 250.

Step by step solution

01

– Write the formulae used

Associative property of multiplication:

a鈰�b鈰�c=a鈰�b鈰�c

Commutative property of multiplication:

a鈰�b=b鈰�a

Inverse property of multiplication:

localid="1648218764262" a鈰�1a=1a鈰�a=1

02

– Write the given information

The expression given is

53鈰�25鈰�3鈰�2

03

- DESCRIPTION OF STEP

To solve given expression use commutative property and associative property to solve it as:

53鈰�25鈰�3鈰�2=25鈰�53鈰�3鈰�2commutativeproperty=25鈰�53鈰�3鈰�2associativeproperty=25鈰�5鈰�1鈰�2inverseproperty=25鈰�5鈰�2=25鈰�10=250
