Answer 1

L.H.S. =

$10 \times (6 - ( - 2)) \\ = 10 \times (6 + 2) \\ = 10 \times 8 \\ = 80$

R.H.S.=

$10 \times 6 - 10 \times ( - 2) \\ = 10 \times ( - 4) \times ( - 2) \\ = 10 \times 8 \\ = 80$

Hence

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

Answer 2

(i)10×[6-(-2)] = 10×6-10×(-2)

$\implies$10×(6+2) = 60+20

$\implies$10×8 = 80

$\implies$80 = 80

(ii)(-15)×[(-7)-(-1)] = (-15)×(-7)-(-15)×(-1)

$\implies$-15 × (-7+1) = 105 - 15

$\implies$-15×(-6) = 90

$\implies$90 = 90
