Question:

Simplify: $4725_w56_h16.png$

A $2858_w22_h16.png$
Explaination

Recall that the multiplication of terms sharing the same base can be simplified by adding the exponents:
$7006_w122_h20.png$
If this rule is forgotten, you can quickly derive it by considering the simple case of $8103_w54_h16.png$, which can be rewritten as $2187_w72_h12.png$, or $2777_w15_h16.png$. The expression in this case, then, can be simplified as: $4521_w161_h16.png$
