If a=24,b=4 and c=2 verify whether (a÷b)÷c=a÷(b÷c)
Step 1; Find the value of (a÷b)÷c
(a÷b)÷c =(24÷4)÷2
=6÷2
=3
Step 2; Find the value of a÷(b÷c)
a÷(b÷c) =24÷(4÷2)
=24÷2
=12
Hence, (a÷b)÷c ≠ a÷(b÷c) is verified.
If A = {1, 2, 3}, B = {4} and C = {5}, then verify that :
(i) A×(B∪C)=(A×B)∪(A×C)
(ii) A×(B∩C)=(A×B)∩(A×C)
(iii) A×(B−C)=(A×B)−(A×C)
Verify the cyclic symmetry of the following expressions if a, b and c are the variables:
(1) a(b − c) + b(c − a) + c(a − b)
(2) ab(a + b) + bc(b + c) + ca(c + a)
(3) a2b(a − b) + b2c(b − c) + c2a(c − a)
(4) a2(a + b) + b2(b + c) + c2(c + a)
(5) ab2(a − b) + bc2(b − c) + ca2(c − a)
