Simplify y^20 ÷ y^11: Laws of Exponents Practice

Insert the corresponding expression:

$\frac{y^{20^{}}}{y^{11}}=$

We are given the expression: $\frac{y^{20}}{y^{11}}$

To solve this, we will use the rule for exponents known as the Power of a Quotient Rule, which states that when you divide two expressions with the same base, you can subtract the exponents: $\frac{a^m}{a^n} = a^{m-n}$.

Applying this rule to our expression:

$\frac{y^{20}}{y^{11}} = y^{20-11}$

After simplifying, we have:

$y^{9}$

The solution to the question is: $y^{9}$
