Verify a×(b-c)=a×b-a×c for a=2/3,b=-1/7 and c=3/5 – InterviewSolution

1.

Verify a×(b-c)=a×b-a×c for a=2/3,b=-1/7 and c=3/5

Answer»

Answer:

2/3(-1/7-3/5)=2/3(-2/7-2/3)3/5

2/3(-5-21/35)=2/3(-6-14/21)3/5

2/3(-26/35)=2/3(-20/21)3/5

2/3(-26/35)=2/3(-4/7)

-52/105=-8/21

52(21)=105(8)

192=840

91=420
