Question

verify (p+q)+r=p+(q+r)when:
p=3/7,q=-3/7,r=1/7​

Answer 1

Step-by-step explanation:

(p+q)+r=p+(q+r)

L.H.S=

$( \frac{3}{7} + ( - \frac{3}{7})) + \frac{1}{7}$

=1/7

R.H.S=

$\frac{3}{7} + ( \frac{ - 3}{7} + \frac{1}{7})$

=1/7

L.H.S=R.H.S

Answer 2

Answer:

From LHS

(p+q)+r

p=3/7; q=-3/7;r=1/7

(3/7-3/7)+1/7

0+1/7

1/7

, From RHS

P+(q+r)

3/7+(-3/7+1/7)

3/7-2/7

1/7 RHS PROVED
