Math tutorial for adding and subtracting radical expressions

What is the primary benefit of using a factor tree when dealing with numbers?

• It helps in identifying square numbers.

• It makes calculations faster.

• It eliminates the need for multiplication.

• It provides exact decimal values.

When encountering a square number like 25 in a factor tree, what should you do?

• Convert it into a decimal.

• Leave it as is to simplify calculations.

• Break it down into smaller factors.

• Ignore it and move to the next number.

How can recognizing square numbers like 9 and 16 help in factor trees?

• They can be used to simplify the factorization process.

• They can be used to find prime numbers.

• They can be ignored to save time.

• They can be converted into fractions.

What is important to remember when simplifying expressions with square roots?

• Combine only terms with the same radicand.

• Always convert them to decimals.

• Ignore the coefficients.

• Add all terms regardless of the radicand.

In the expression 5√3 - 4√2, why can't you combine the terms?

• They have different coefficients.

• They are both positive.

• They are both negative.

• They have different radicands.
