Which equations illustrate the commutative property of multiplication?

choose exactly two answers that are correct.

a.

b.
–8 • (4 • 1) = (–8 • 4) • 1

c.
–4 • (5 + 7.1) = –4 • 5 + (–4) • 7.1

d.
–8 • (5 + 3.1) = (5 + 3.1) • (–8)

Commutative law states that in multiplication a x b = b x a (i.e. the product remains the same irrespective of the order of presentation).
From the options
Option B illustrates associative property
Option C illustrates distributive property
Option D illustrates commutative property (i.e. -8 x (5 + 3.1) = (5 + 3.1) x (-8))
