TRUE or FALSE.

Similar radicals can be added or subtracted.

• TRUE

• FALSE

The first step in adding or subtracting similar radicals is to combine like terms. 

• TRUE

• FALSE

TRUE OR FALSE

To add or subtract radical expression having fractional radicand you need to rationalize the denominator before simplifying.

• TRUE

• FALSE

You cannot add or subtract radical expression if they have different indices and the same radicand. 

• TRUE

• FALSE

The last step in adding or subtracting radical expression is to reduce the answer in its simplest form.

• TRUE

• FALSE

TRUE or FALSE

To add similar radicals, add the coefficient then multiply the radicand.

• TRUE
