What is another term for a radical in mathematics?

• Variable

• Exponent

• Coefficient

• Square root

Why do we simplify radicals?

• To make them easier to calculate by hand

• To get a rounded decimal answer

• To write the answer in exact form

• Because it's required by mathematical laws

What is the first step in simplifying a radical?

• Make a factor tree

• Identify pairs of numbers

• Find the square root

• Divide by the smallest prime number

What do you do with pairs of numbers in a factor tree when simplifying radicals?

• Leave them under the radical

• Take one out of the radical

• Multiply them

• Add them together

How do you simplify the square root of 80?

• 2 radical 10
