Simplify 5 + (sqrt)50/10, (cubedrt)24x^3y^8 + (cubedrt)81...

[debmcgary]

I need to simplify the following problems:

5+(sqrt)50/10

and

(cubedrt)24x^3y^8 + (cubedrt)81x^6y^2

The first one you've already posted elsewhere.

For the second one, I can't tell what you mean. I will guess that "(cubedrt)" means "the cube root of", but your non-standard use of parentheses makes it impossible to tell what all is inside the root. (Using the formatting explained in "Karl's Notes", in the link in the "Forum Help" pull-down menu at the very top of the page, would be very helpful.)

Do you mean any of the following?

. . . . .cbrt[24]x³y⁸ + cbrt[81]x⁶y²

. . . . .cbrt[24x³]y⁸ + cbrt[81x⁶]y²

. . . . .cbrt[24x³y⁸] + cbrt[81x⁶y²]

. . . . .cbrt[24x³y⁸ + cbrt[81x⁶y²]]

Or do you mean something else? How far have you gotten in the simplification process?

Please show all of your steps. Thank you.
