Understanding Exponents and Division

When dealing with exponents, it's essential to understand the rules of division and how they apply to expressions with exponents. In this article, we'll focus on simplifying the expression $k^{-10} \div 10k^{-15}$.

The Rules of Exponent Division

When dividing two numbers with exponents, we subtract the exponents. This rule applies to both positive and negative exponents. For example, $a^m \div a^n = a^{m-n}$.

Applying the Rules to the Given Expression

Now, let's apply the rules of exponent division to the given expression:

$k^{-10} \div 10k^{-15}$

To simplify this expression, we need to divide the two numbers with exponents. We can rewrite the expression as:

$\frac{k^{-10}}{10k^{-15}}$

Simplifying the Expression

Using the rule of exponent division, we can simplify the expression as follows:

$\frac{k^{-10}}{10k^{-15}} = \frac{1}{10} \cdot k^{-10 + 15}$

Evaluating the Exponent

Now, let's evaluate the exponent:

$k^{-10 + 15} = k^5$

Simplifying the Expression Further

Now that we have evaluated the exponent, we can simplify the expression further:

$\frac{1}{10} \cdot k^5$

The Final Answer

So, the final answer is:

$\boxed{\frac{k^5}{10}}$
