  1.    $100000 × 10 × 100 × 1000 ÷10 ÷ 100 ÷ 1000$
    = 100000 ×10 ×100 ×1000 ÷ 10 ÷ 100 ÷ 1000
    = $100000$ 
    (Phần gạch dưới là mình gạch bỏ nó đi nhé)

  2. 100000 × 10 × 100 × 1000 ÷ 10 ÷ 100 ÷ 1000
    = 100000 × ( 10 ÷ 10 ) × ( 100 ÷ 100 ) × ( 1000 ÷ 1000 )
    = 100000 × 1 × 1 × 1 
    = 100000
