Providing the radical has then just add/subtract.
e.g.
4sqrt(3) + (/-)7sqrt(3) .
The radical has tha same coefficient of 'sqrt(3)'
Hence it becomes 11sqrt(3) ( or - 3sqrt(3))
However, if the radicals are different then
4sqrt(3) + 7sqrt(2) . cannot be taken any further.

What makes radical expressions like terms?
Radical expressions are called like radical expressionsif the indexes are the same and the radicands are identical.
After you add or subtract two rational expressions the next step is to put your answer in form?
reduced form $ara ;)
Why is it important to simplify radical expressions before subtracting or adding and how is adding a radical expression similar to adding a polynomial expression and provide an example?

Are all radical expressions irrational?
No. Radical(9) is +3 or -3, both of which are rational.
Does decrease mean to add or subtract?
wich one
Can you add or subtract under the radical?
No, you cannot add or subtract under the radical. The radical represents the square root function, and it only operates on the number or expression that is inside the radical. To add or subtract, you need to simplify the expressions inside the radical first.
If you need to add radical expressions that have different radicands you should determine whether you can subtract a radical expression and then combine like terms?
false , i tried it on apex so its right
How is combining like terms similar to adding and subtracting square roots?
In surd form, square roots need to be have the same radical term before you can add or subtract them. However, unlike in algebraic expressions, it is possible to add or subtract square roots using approximate (decimal) values.
If you need to ass radical expressions that have different radicands you should determine whether or not you can subtract a radical expression and then combine like tearms. true or false?
true
How do you know if you will subtract or add in simplifying algebraic expressions?
Only like terms can be subtracted or added in algebraic expressions.
After you add or subtract two rational expressions it's a good idea to see if you can your answer?
reduce
What are the Rules for subtracting radicals?
similar-a similar radicand is to add or subtract similar radicals we simply add and subtract there coefficients and Anex to the sum of their common radical part.
Why do the properties for solving for exponential expressions apply to radical expressions as well?
A radical is an exponent, stupid.
