If a=64,b=8 and c=4 verify that (a÷b)÷c≠a÷( b÷c)
Step 1: Find the value of (a÷b)÷c
a÷(b÷c) =(64÷8)÷4
=8÷4
=2
Step 2: Find the value of a÷(b÷c)
a÷(b÷c) =64÷(8÷4)
=64÷2
=32
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)
If a=24,b=4 and c=2 verify whether (a÷b)÷c=a÷(b÷c)
Verify that a(b+c)≠ab+ac for each of the following values of a, band c.
a=12,b=-4,c=2
