Q: How do I add radicals like this: ?
A: = =
Note that this is analogous to 2x + 4x = 6x, where the terms act similar to the variable x.
Let’s look at some more examples:
= =


Q: How do I add radicals like this: ? A: = = Note that this is analogous to 2x + 4x = 6x, where the terms act similar to the variable x. Let’s look at some more examples: = = Q: What if I have to add radicals, but the radicals are different? I am trying to add . A: You can’t add those, or simplify any further without a calculator. You just have to leave it as it is, because the square roots are different (3 and 5). = Let’s look at . . . → Read More: Adding Unlike Radicals Q: How do I subtract radicals like this: ? A: Subtracting radicals is very similar to adding radicals. = = Q: Simplify the radical expression by rationalizing the denominator: . Thanks. A: First let’s simplify the bottom, by splitting the up into / Â (note that = 1) To rationalize the denominator, you just multiply by . You are allowed to do this because really you are just multiplying by 1. Note . . . → Read More: Rationalize the denominator
