8 sqrt v^2-sqrt v^4-sqrt 9v^2+sqrt 16v4

Answer 1

\[\large 8\sqrt{v^2}-\sqrt{v^4}-\sqrt{9v^2}+\sqrt{16v^4} \]
this?

Answer 2

yes

Answer 3

\[\large 8\sqrt{v^2}-\sqrt{v^4}-\sqrt{9v^2}+\sqrt{16v^4}=8v-v^2-3v+4v^2 \]
can you take it from here?

Answer 4

no im still stuck

Answer 5

combine the v^2 terms: 4v^2 - v^2
combine the v terms: 8v - 3v

string the results with a "+"

Answer 6

4v+5v

Answer 7

no... try again...

Answer 8

3v^2+5v
