Question

2. Verify that a =(b+c)+(a=b)+(a=c) for each of the following values of a, b and
(a) a = 12, b = -4, c= 2
(b) a=(-10), b = 1, c= 1​

Answer 1

Answer:

a÷(b÷c)



=(a÷b)÷(a÷c)

LHS=a÷(b+c)=

b+c

a

RHS=(a÷b)+(a÷c)=

b

a

+

c

a

=

bc

ac+ab

∴LHS



=RHS

a=−10,b=1 and c=1

LHS=a÷(b÷c)=(−10)÷(1÷1)

=−10÷1=

1

−10

=−10

RHS=(a÷b)+(a÷c)=

1

−10

+

1

−10

=(−10)+(−10)=−10−10=−20

∴LHS
