Adding and Subtracting Radicals Expressions with Variables

To add and subtract radicals, add and subtract like radicals or similar radicals.

• TRUE

• FALSE

Adding and subtracting radical expressions is very much similar to adding and subtracting similar terms of polynomials.

• TRUE

• FALSE

2√5 + 4√5 =

• 6√10

• 8√10

• 8√5

• 6√5

• 5∛27
• 7∛3
• 15
• 8∛3

• 8√6

• 8√12

• 12√6

• 12√12

Adding and subtracting radical expressions is very much similar to adding and subtracting similar terms of polynomials.

• TRUE

• FALSE

√5

• 11√5

• 11√10

• 5√5

• 12√10

√5 + √20

• 5

• 25

• 3√5

• 2√3

Solve: 3√6 + 3√2 - 5√6 - 2√2

• -2√6 + √2

• -√2

• 6√2 - 7√6

• 2√6 - √2

Write with radical. Assume that all variables represent positive real numbers.
