☹️

Answer 1

(a)

Given: 12 * 102

= > 12 * (100 + 2)

We know that a * (b + c) = a * b + a * c

= > 12 * 100 + 12 * 2

= > 1200 + 24

= > 1224.



(b)

Given : 4 * (9 + 16)

It is in the form of a * (b + c) = a * b + a * c.

= > 4 * 9 + 4 * 16

= > 36 + 64

= > 100.




Hope this helps!

Answer 2

a. commutative property
12×102=102×12
1224=1224
b. We won't get which property. without property,
4×(25)
100.
Therefore ,a.1224,b.100.
Hope this helps you.
