How is adding radical expressions similar to adding polynomial expressions?

You add the numbers in front of the radical signs, just as you

add the coefficients in front of the like variables

Notice the similarities:

3 cats + 2 cats = 5 cats

3x + 2x = 5x

3√2 + 2√2 = 5√2

1 dog + 6 dogs - 4 dogs = 3 dogs

x + 6x - 4x = 3x

√5 + 6√5 - 4√5 = 3√5
