Question

e) If a=3, b= -2, c= -1, verify that:
bxcx a = a xbx c= cxa xb​

Answer 1

Question:

Verify that:  b × c × a = a × b × c = c × a × b​

Given:

a = 3, b = -2, c = -1

Step-by-step explanation:

• Lets divide the question in three parts:
• We have the following equations to solve :

1.    b × c × a
2.    a × b × c
3.    c × a × b​

• And in last we'll verify their equality.
• Lets solve the first equation,  b × c × a
• a = 3, b = -2, c = -1
• = -2 × -1 × 3
• = 2 × 3
• = - 6

• Lets solve the second equation,  a × b × c
• = 3 × -2 × -1
• = -6 × -1
• = 6

• Lets solve the third equation,  c × a × b​

• = -1 × 3 × -2
• = -3 ×-2
• = 6

As, equation 1, equation 2 and equation 3 are equal. We can say that b × c × a = a × b × c= c × a × b​ is verified for  a = 3, b = -2, c = -1.

Hence, verified.
