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.
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 do you add and subtract radical fractions similar?
Similar radicalssuch as ... 5(sq root 7) + 3(sq root 7) are similar because the radical has the same root index and the same number inside the radical. Like variables they can have different coefficients. 2x and 5x are similar ( called like terms) add the coefficients. 2x + 5x = 7x similarly 5(sq root 7) + 3(sq root 7) = 8(sq root 7)
What is the opposite for add?
The opposite of add is subtract.
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.
