To rewrite the irrational square root of \( 72 \) as the product of an integer and another irrational square root, we first factor \( 72 \) into its prime factors:

\[ 72 = 2^3 \times 3^2 \]

Next, we can express \( \sqrt{72} \) as follows:

\[ \sqrt{72} = \sqrt{2^3 \times 3^2} \]

We can separate this into two parts:

\[ \sqrt{72} = \sqrt{2^2 \times 2^1 \times 3^2} \]

Using the property of square roots that states \( \sqrt{a \times b} = \sqrt{a} \times \sqrt{b} \), we can rewrite this as:

\[ \sqrt{72} = \sqrt{2^2} \times \sqrt{2^1} \times \sqrt{3^2} \]

Calculating the square roots of the perfect squares:

\[ \sqrt{2^2} = 2 \quad \text{and} \quad \sqrt{3^2} = 3 \]

Thus, we have:

\[ \sqrt{72} = 2 \times 3 \times \sqrt{2} = 6 \sqrt{2} \]

Therefore, the square root of \( 72 \) rewritten as the product of an integer and another irrational square root is:

\[ \sqrt{72} = 6 \sqrt{2} \]
