Question

Evaluate 105×106 without multiplying directly​

Answer 1

Answer:

105 × 106

= (100+5) (100+6)

= 100(100)+100(6) + 5(100) + 5(6)

= 10000+600 + 500+30

= 10000+1100+30

= 11130

Hope it helps

Answer 2

$105 \times 106 \\ = (100 + 5) \times (100 + 6) \\ = {(100)}^{2} + (5 + 6)(100) + (5 \times 6) \\ 10000 + 1100 + 30 \\ 11130$
