\[
\sqrt{16 y^{4}}
\]
Assume that the variable $y$ represents a positive real number.
Solution
Solution Steps
To simplify the square root of a perfect square monomial, we need to find the square root of each factor separately. For the given expression \(\sqrt{16 y^{4}}\), we can take the square root of 16 and the square root of \(y^4\) independently.
Step 1: Identify the Expression
We start with the expression \(\sqrt{16 y^{4}}\).
Step 2: Simplify the Numerical Part
The square root of the numerical part is calculated as follows:
\[
\sqrt{16} = 4
\]
Step 3: Simplify the Variable Part
Next, we simplify the variable part:
\[
\sqrt{y^{4}} = y^{\frac{4}{2}} = y^{2}
\]
Step 4: Combine the Results
Combining both parts, we have:
\[
\sqrt{16 y^{4}} = 4y^{2}
\]
