Question

If a = (– 5), b = (– 4) and c = 2, verify that (a × b) × c = a × (b × c)

Answer 1

Answer:

(-5(-4) (2)=(-5) (-4(2))

20(2)=(-5) (-8)

40=40

Answer 2

$\huge{\underline{\underline{\red{\mathfrak{Solution:}}}}}$

$\bf{\large{\blue{Given}}}$

$a = ( - 5)$

$b = ( - 4)$

$c = 2$

$\bf{\large{\green{Verify:}}}$

(a × b) × c = a × (b × c)

$\bf{\large{\pink{Then:}}}$

$( -5\times - 4) \times 2 = ( - 5) \times (( - 4) \times 2)$

$(- 20) \times 2 = ( - 5) \times ( - 8)$

$( - 40) = ( - 40)$

$\bf{\large{\orange{L.H.S=R.H.S, Hence\: Verified}}}$
