Question

explain why The radical expressions shown can be combined to become one radical expression through addition or subtraction

Answer 1

The two terms cannot be combined by addition or subtraction

Step-by-step explanation:

Here, we answered that the two radicals can be combined. However, these two cannot be combined. The first answer should be false

We can have the second root as:

`\sqrt[]{12}\text{ = }\sqrt[]{4*3\text{ }}\text{ = }\sqrt[]{4}\text{ }*\sqrt[]{3\text{ }}\text{ = 2}\sqrt[]{3}`

Now, since they both do not have same root terms, they cannot be combined via addition or subtraction
