Question

I need some help with 7 Adding and Subtracting Radical Expressions problems. :)

Answer 1

Find the exact value of the radical expression in simplest form.\[\sqrt{16y^3}-\sqrt{y^3}\]

Answer 2

Please explain how you got the answer, and I'll try some of te others on my own- I may need some help though :)

Answer 3

So would the answer be \[8\sqrt{8}\]?

Answer 4

oops, I meant \[4\sqrt{2}\]

Answer 5

Oh, okay :)

Answer 6

So then it beomes \[4y^2\sqrt{y}\]?

Answer 7

\[3y \sqrt{y}\] then... Wow I'm so sorry, my teacher wouldn't explain it well.

Answer 8

I haven't gotten to multiplying and dividing yet, but that's next :)

Answer 9

Oh, I see! I'm going to try the next problem, but I might need some help... It's Find the exact value of the radical expression in simplest form. \[5\sqrt{2}+\sqrt{2}\]
