First you need to multiply the out side numbers with each other.
Then you need to multiply the numbers inside the radicals together.
If the number inside the radical is a perfect square then you need to take the square root and multiply it by the number outside. for example.
3√2 x 2 √6 = 6√12 then you have to simplify the Radical 12 √4 √3 Then 4 is a perfect square so you must make it 2 6 x 2 √3 Then since the radical 4 turns into a regular 2 you have to multiply it by the number outside of the radical which is 6 12 √3 That is the final answer BOOM QUESADILLA SANDWICH!
Background Information
Steps
3√2 x 2 √6 = 6√12 then you have to simplify the Radical 12
√4 √3 Then 4 is a perfect square so you must make it 2
6 x 2 √3 Then since the radical 4 turns into a regular 2 you have to multiply it by the number outside of the radical which is 6
12 √3 That is the final answer BOOM QUESADILLA SANDWICH!
