Check which of the following satisfy the commutative property of multiplication.(a)$(2\times10) + (2\times7) = 2 \times (10+7)$(b) $10\times2 = 2\times 10$(c) $3\times8 = 8\times 3$
Given :
The given expression is (a) $(2\times10) + (2\times7) = 2 \times (10+7)$ (b) $2 \times 10 = 10 \times 2$ (c) $8 \times 3 = 3 \times 8$
To do :
We have to check which of the given expressions satisfy the commutative property of multiplication.
Solution :
Commutative property for multiplication :
$a\times b = b \times a $
(a) $(2\times10) + (2\times7) = 2 \times (10+7)$ is not satisfy commutative property for multiplication.
(b)$2 \times 10 = 10 \times 2$
$ 20 = 20$
LHS = RHS.
Therefore, $2 \times 10 = 10 \times 2$ follows commutative property for multiplication.
(c)$8 \times 3 = 3 \times 8$
$ 24 = 24$
LHS = RHS.
Therefore, $8 \times 3 = 3 \times 8$ follows commutative property for multiplication.
