6130.5

Short Answer

Expert verified

Value of given expression is 39.

Step by step solution

01

Step-1- Concept of commutative property and associative property of multiplication

The commutative property is a math rule says thatthe order in which we multiply numbers does not change the final product.

A脳B=B脳A

The associative property of multiplication states that the product of three or more numbers remains the same regardless of how the numbers are grouped,

A脳B脳C=A脳B脳C.

02

Step-2-Evaluating given expression

6130.5

Using Order of operations,

6130.5=6130.5.

Using Commutative property,

6130.5=1360.5.

Using associative property,

6(13)(0.5)=13(6(0.5))6(13)(0.5)=13(3)6(13)(0.5)=39

03

Step-3-Conclusion

Therefore, the value of given expression is 39.
