The correct Answer is:
To solve the expression \(\frac{\sqrt{a} \times \sqrt{b}}{3\sqrt{a} - 2\sqrt{b}}\), we can follow these steps: ### Step 1: Rewrite the expression The given expression is: \[ \frac{\sqrt{a} \times \sqrt{b}}{3\sqrt{a} - 2\sqrt{b}} \] ### Step 2: Factor out \(\sqrt{a}\) from the denominator In the denominator, we can factor out \(\sqrt{a}\): \[ 3\sqrt{a} - 2\sqrt{b} = \sqrt{a}(3 - 2\frac{\sqrt{b}}{\sqrt{a}}) \] ### Step 3: Substitute the factored form back into the expression Now, substituting the factored form back into the expression gives us: \[ \frac{\sqrt{a} \times \sqrt{b}}{\sqrt{a}(3 - 2\frac{\sqrt{b}}{\sqrt{a}})} \] ### Step 4: Cancel \(\sqrt{a}\) from the numerator and denominator Since \(\sqrt{a}\) is common in both the numerator and the denominator, we can cancel it out (assuming \(\sqrt{a} \neq 0\)): \[ \frac{\sqrt{b}}{3 - 2\frac{\sqrt{b}}{\sqrt{a}}} \] ### Step 5: Simplify further if possible However, we can also express the denominator in a simpler form: \[ 3 - 2\frac{\sqrt{b}}{\sqrt{a}} = 3 - 2\sqrt{\frac{b}{a}} \] Thus, the expression simplifies to: \[ \frac{\sqrt{b}}{3 - 2\sqrt{\frac{b}{a}}} \] ### Final Result The expression \(\frac{\sqrt{a} \times \sqrt{b}}{3\sqrt{a} - 2\sqrt{b}}\) is equivalent to: \[ \frac{\sqrt{b}}{3 - 2\sqrt{\frac{b}{a}}} \]
