Answer 2

To solve the expression ∛(2+√5) + ∛(2-√5), we can simplify it using the properties of cube roots.

Let's begin by simplifying each cube root individually:

∛(2+√5) = ∛2 + ∛√5

∛(2-√5) = ∛2 - ∛√5

Now, we can substitute these simplified expressions back into the original equation:

∛(2+√5) + ∛(2-√5) = (∛2 + ∛√5) + (∛2 - ∛√5)

Notice that the terms with the cube roots of √5 cancel each other out, leaving us with:

= ∛2 + ∛2

Since both terms are the same, we can simplify further:

= 2∛2

Therefore, the solution to the expression ∛(2+√5) + ∛(2-√5) is 2∛2.
