Question

Evaluate the following using a suitable property.
a) 12345 × 229 − 12345 × 129
MUST SAY WHICH PROPERTY IS USED

Answer 1

Answer:

(12345×229)-(12345×129)

2827005-1592505

=1234500

Step-by-step explanation:

You can use BODMASS property

Answer 2

Step-by-step explanation:

this will be distributive property

because

12345× 229 - 12345× 129

= 12345( 229-129)

= 12345× 100

= 1234500

let's verify

12345× 229 = 2827005 -- equation 1

and 12345× 129 = 1592505 -- equation 2

equation 1- equation 2 = 1234500

therefore it's correct that it obeys distributive law and answer will be 1234500
