Question

verify that a + b = b + a for each of the following a = 4/5; b=-3\10​

Answer 1

Answer:

a+b

=4/5 + 3/10

8/10 + 3/10

11/10

b+a

=3/10 + 4/5

3/10 + 8/10

11/10

hence proved,

11/10 = 11/10

a+b=b+a

Answer 2

Answer:

the property is commutative

Explanation:

4/5+3/10=3/10+4/5

4\5*2\2=8/10[LHS]

now add 8/10+3/10=9/10{lhs]

3/10 +4/5[RHS]

ADD;3/10 AND4/5 TO GET 9 /10=

THUS LHS =RHS
