The correct Answer is:
To find the simplest rationalizing factor of \(\sqrt{27}\), we can follow these steps: ### Step 1: Simplify \(\sqrt{27}\) We start by simplifying \(\sqrt{27}\). The number 27 can be expressed as a product of its prime factors: \[ 27 = 3^3 \] Now, we can write: \[ \sqrt{27} = \sqrt{3^3} \] ### Step 2: Apply the property of square roots Using the property of square roots, we can separate the factors: \[ \sqrt{27} = \sqrt{3^2 \cdot 3} = \sqrt{3^2} \cdot \sqrt{3} \] Since \(\sqrt{3^2} = 3\), we have: \[ \sqrt{27} = 3\sqrt{3} \] ### Step 3: Identify the rationalizing factor The rationalizing factor is essentially what we need to multiply \(\sqrt{27}\) by to eliminate the square root in the denominator. In this case, since we have \(\sqrt{3}\) as part of our simplified expression, the simplest rationalizing factor of \(\sqrt{27}\) is: \[ \sqrt{3} \] ### Final Answer Thus, the simplest rationalizing factor of \(\sqrt{27}\) is: \[ \sqrt{3} \] ---
