To simplify the expression \( \frac{t(400)}{t(100)} \) using the Quotient Rule of Integer Exponents, we apply the rule that states \( \frac{a^m}{a^n} = a^{m-n} \).
Here, we can treat \( t(400) \) as \( t^{400} \) and \( t(100) \) as \( t^{100} \).
Using the Quotient Rule:
\[ \frac{t^{400}}{t^{100}} = t^{400 - 100} = t^{300}. \]
Thus, the simplified expression is:
t(300).
