B) (axb)xc= a(bxc)
C) (a-b)-c=a-(b-c)
D) (a+b):C #a=(b+c)
a) A,B
b) A,C
CA,D
d) B,C​

Answer 1

Answer:

a) A, B is the correct answer

Step-by-step explanation:

Answer 2

Answer:

A,B is the correct option.

Step-by-step explanation:

Option A,

( a+b)+c = a+(6+c)

if a=1. ( or any number )

b=6 , c=2 (or any other number)

then we find same means both are equal.

= (1+6)+2 = 1+(6+2)

= 7 + 2 = 1 + 8

= 9 = 9 Ans.

Option B,

(a×b)×c = a(b×c)

if a=1, b=6, c=2

therefore,

= (1×6)×2 = 1(6×2)

= 6×2 = 1×12

= 12 = 12 Ans.

therefore Option A is the correct ans that is the
