The Quotient Rule of Integer Exponents states that when you divide two exponential expressions with the same base, you subtract the exponents. The correct expression is:

\[ \frac{x^a}{x^b} = x^{a-b} \]

So, the first option is the correct representation of the Quotient Rule.

Simplify x^675 over x^453.

To simplify the expression \(\frac{x^{675}}{x^{453}}\), you can apply the Quotient Rule of Integer Exponents, which states that:

\[ \frac{x^a}{x^b} = x^{a-b} \]

In this case, \(a = 675\) and \(b = 453\). So, we have:

\[ \frac{x^{675}}{x^{453}} = x^{675 - 453} \]

Now, calculate \(675 - 453\):

\[ 675 - 453 = 222 \]

Therefore, the simplified expression is:

\[ \frac{x^{675}}{x^{453}} = x^{222} \]

What is the missing exponent in the following equation? e^? over e^65 = e^38

To find the missing exponent in the equation

\[ \frac{e^{?}}{e^{65}} = e^{38}, \]

you can use the Quotient Rule of Exponents, which states:

\[ \frac{e^a}{e^b} = e^{a-b}. \]

Applying this rule, we can rewrite the left side of the equation:

\[ e^{? - 65} = e^{38}. \]

Since the bases are the same (both are \(e\)), we can set the exponents equal to each other:

\[ ? - 65 = 38. \]

To solve for the missing exponent \(?\), add 65 to both sides:

\[ ? = 38 + 65. \]

Calculating the right side:

\[ ? = 103. \]

Therefore, the missing exponent is \(103\).

Simplify 13^12 divided by 13^-10.

To simplify the expression \(\frac{13^{12}}{13^{-10}}\), you can apply the Quotient Rule of Exponents, which states:

\[ \frac{x^a}{x^b} = x^{a-b}. \]

In this case, let \(a = 12\) and \(b = -10\). Thus, we have:

\[ \frac{13^{12}}{13^{-10}} = 13^{12 - (-10)}. \]

This simplifies to:

\[ 13^{12 + 10} = 13^{22}. \]

Therefore, the simplified expression is:

\[ \frac{13^{12}}{13^{-10}} = 13^{22}. \]

Simplify 4^13 divided by 3^-5.

To simplify the expression \(\frac{4^{13}}{3^{-5}}\), you can approach it by recalling that dividing by a negative exponent is equivalent to multiplying by the positive exponent:

\[ \frac{4^{13}}{3^{-5}} = 4^{13} \cdot 3^{5}. \]

This gives you the final expression:

\[ 4^{13} \cdot 3^5. \]

Since these two terms are multiplication of different bases, \(4^{13}\) and \(3^{5}\) cannot be simplified further as a single term. Thus, the simplified expression is:

\[ 4^{13} \cdot 3^{5}. \]
