Question

Which of the following correctly demonstrates the use of the commutative property of multiplication

A. 11(b+z)=11z
B. 3(b^10+4)= 3 ( 4+b^10)3
C. 2 (b10+z^11)=(b^10+z^11)x2
D. z^11x2=z^11+2

Answer 1

B

Explanation:

The option that correctly demonstrates the use of the commutative property of multiplication is:

B. 3(b^10+4) = 3(4+b^10)

Answer 2

C. 2(b^10 + z^11) = (b^10 + z^11) × 2

Explanation:

Commutative property of multiplication:

a × b = b × a

In 2(b^10 + z^11) = (b^10 + z^11) × 2,

2 times the quantity in parentheses equals the quantity times 2.

That is an application of the associative property of multiplication.
