What is a Surd

What is the main reason for using surds instead of decimal approximations?

• To avoid rounding errors and maintain accuracy

• To make calculations easier

• To convert numbers into fractions

• To simplify complex equations

Which of the following is a characteristic of a surd?

• It can be expressed as a whole number

• It is a repeating decimal

• It is a non-repeating, non-terminating decimal

• It can be written as a fraction

How can you determine if a root is not a surd?

• If it cannot be expressed as a fraction

• If it can be expressed as a whole number

• If it is a non-repeating decimal

• If it is a non-terminating decimal

What should you do if a number is a surd?

• Leave it in root form

• Convert it to a fraction

• Express it as a repeating decimal

• Round it to the nearest whole number

Why is it important to identify surds correctly?

• To simplify mathematical expressions

• To convert them into whole numbers

• To make them easier to memorize

• To ensure calculations are exact
