Question 983242
4√7+3√7-8 3√7

<pre>
Why is there a space between the 8 and the 3?  Is that supposed to be 83?

Why did you say "That one is a cube?" Are they supposed to be cube roots and
not square roots?

If 8 3 means 83 then to do:

4&#8730;7+3&#8730;7-83&#8730;7

Factor out the &#8730;7

&#8730;7(4+3-83)

&#8730;7(-76)

-76&#8730;7
