Example 3

medium
Multiply 6โ‹…10\sqrt{6} \cdot \sqrt{10} and simplify.

Solution

  1. 1
    6โ‹…10=60=4โ‹…15=215\sqrt{6} \cdot \sqrt{10} = \sqrt{60} = \sqrt{4 \cdot 15} = 2\sqrt{15}.
  2. 2
    Check: 6ร—10=606 \times 10 = 60 and (2)2ร—15=60(2)^2 \times 15 = 60 โœ“

Answer

2152\sqrt{15}
The product rule aโ‹…b=ab\sqrt{a} \cdot \sqrt{b} = \sqrt{ab} combines the radicands. Then simplify the result by extracting any perfect square factors.

About Radical Operations

Adding, subtracting, and multiplying expressions that contain radicals. Like terms (same radicand) can be combined for addition and subtraction; for multiplication, use aโ‹…b=ab\sqrt{a} \cdot \sqrt{b} = \sqrt{ab}.
