00:03 The product of the square root of number (N) and the square root of number (M)
00:07 equals the square root of their product (M times N)
00:12 Apply this formula to our exercise
00:15 This is the solution

Step-by-Step Solution

To solve this problem, we can use the product property of square roots.

  • Step 1: Recognize the expression ab \sqrt{a} \cdot \sqrt{b} .
  • Step 2: Apply the product property: ab=ab \sqrt{a} \cdot \sqrt{b} = \sqrt{a \cdot b} .

This tells us that the original expression, ab \sqrt{a} \cdot \sqrt{b} , simplifies to ab \sqrt{a \cdot b} .

Thus, the equivalent expression is ab \sqrt{a \cdot b} .

Among the given choices, choice 2 ab \sqrt{a\cdot b} is the correct one.

Answer

ab \sqrt{a\cdot b}
