  1. $\text{ $99^{96}$ + $99^{97}$ + $99^{98}$ + $99^{99}$ }$
    $\text{ $96^{96}$ × ( 1 + 99 + $99^{2}$ + $99^{3}$ )}$
    $\text{ $96^{96}$ × ( 100 + $99^{2}$ ( 1 + 99 ))}$
    $\text{ $96^{96}$ × ( 100 × 1 + $99^{2}$ ×100 ) }$
    $\text{ $96^{96}$ × ( 100 × ( $99^{2}$ + 1 ) $\vdots$ 100}$

  2. Lời giải và giải thích chi tiết:
    $99^{96}$ +$99^{97}$+$99^{98}$ +$99^{99}$
    $99^{96}$$(1+99)$ +$99^{98}$$(1+99)$
    $99^{96}$$100$ +$99^{98}$$100$
    =100($99^{96}$ +$99^{98}$) chia hết cho 100
