Question

solve using suitable property
1. 279*96+279*4
2, 172+172*99

Answer 1

ANSWER:

1.) 27900

2.) 17200

Step-by-step explanation:

1.) (279)(96) + (279)(96)

To solve this sum : let A=279 , B =96 and C =4

we get AB + AC here A is common so let a take common,

A ( B + C )

now we will subsitut values for variables which we assumed in beginning

279 ( 96 + 4 )

279 ( 100 )

=>27900

2.) (172) + 172(99)

here let A = 172 , B = 99 we get

A + AB ,similiarly here also take A as common

we get A ( 1 + B )

now put values of variables which we assumed in starting

We get 172 ( 1 + 99 )

172 ( 100 )

=> 17200
