Smplifying the mulitplication of two radicals, 2 root

The video tutorial explains how to multiply numbers inside radicals, similar to multiplying variables. It demonstrates this concept with examples, showing that radicals can be multiplied both inside and outside the radical sign. The tutorial also covers simplifying radical expressions by breaking them down into simpler components. The lesson concludes with a summary of the key points discussed.

What is the key concept when multiplying numbers inside radicals?

• They cannot be multiplied.

• They can be multiplied like variables.

• They must be like terms.

• They can be added directly.

Which of the following is true about adding radicals?

• Radicals can always be added.

• Radicals can never be added.

• Radicals can be added if they have different terms.

• Radicals can be added if they are like terms.

In the example given, what is the result of multiplying sqrt(4) and sqrt(9)?

• 6

• 12

• 3

• 9

What is the simplified form of 6 times radical 12?

• 6 times radical 6

• 6 times radical 4 times radical 3

• 12 times radical 3

• 6 times radical 2

How can radical 4 be further simplified?

• Into radical 1 times radical 4.

• Into radical 3 times radical 3.

• Into radical 2 times radical 2.

• It cannot be simplified.
