1. Step-by-step explanation:

   [tex]8 \times 26 \times – 125 = – 2600

   .

   \ – 20 \times6 \times – 5 = – 600.

2. Step-by-step explanation:

   21) × [(- 4) + (- 6)] = [(- 21) × (- 4)] + [(- 21) × (- 6)]

   L.H.S. = (- 21) × [(- 4) + (- 6)]

   = (- 21) × (- 10)

   = 21 × 10 = 210

   R. H.S. = [(- 21) × (- 4)] + [(- 21) × (- 6)]

   = (21 × 4) + (21 × 6)

   = 84 + 126 = 210

   So, (- 21) × [(- 4) + (- 6)]

   = [(- 21) × (- 4)] + [(- 21) × (- 6)].
