Just as you cant add apples and oranges so also you cannot combine unlike radical terms. If not then you cannot combine the two radicals. If these are the same then addition and subtraction are possible.
This shows that they are already in their simplest form. But you might not be able to simplify the addition all the way down to one number. For example the terms.
You reversed the coefficients and the radicals. We call radicals with the same index and the same radicand like radicals to remind us they work the same as like terms. Observe that each of the radicands doesnt have a perfect square factor.
Simplify by adding andor subtracting the radical expressions below. We add and subtract like radicals in the same way we add and subtract like terms. In order to be able to combine radical terms together those terms have to have the same radical part.
Radical expressions are expressions that contain radicals. We know that 3 x 8 x is 11 x Similarly we add 3 x 8 x and the result is 11 x. Like radicals are radical expressions with the same index and the same radicand.
