Question

Let a, b, c be the three rational numbers where a = 23, b = 40 and c = −36 (Verify:
(i) a + (b + c) = (a + b) + c (ii) a × (b × c) – (a × b) × c

Answer 1

Answer:

a=23 , b= 40 and c= -36

Step-by-step explanation:

By using 1 st formula

a+(b+ c) = (a +b) +c

=(23+ 40) + (-36)

= 63 - 36

= 27

By using Second formula

a× (b×c) = (a×b) × c

= ( 23× 40) × (-36)

= 920 × (-36 )

= -33120
