Question

2. Verify the following:
(a) 18* [7 +(-3)]=[18 x 7] + [18 (-3)]​

Answer 1

Answer:

L.H.S.=18* [7 +(-3)]

=18×{4}

L.H.S =72

R.H.S.=[18 x 7] + [18 (-3)]

=126+(-54)

R.H.S.=72

therefore R.H.S=L.H.S.

hence,18* [7 +(-3)]=[18 x 7] + [18 (-3)]

is verified.

Answer 2

18 x [7 +(-3)] = [18 x 7] +[18 x (-3)]

18× [7 - 3] = 126 + [-54]

18× 4 = 126 - 54

72 = 72

LHS = RHS
