a.) +or- 2 sqrt 5
b.) +or- sqrt 5
c.) +or- 4 sqrt 5

Answer 1

Move 80 to other side

Answer 2

x^2=80

Answer 3

okay

Answer 4

Then simplify the root of 80

Answer 5

yes

Answer 6

4 * 20?

Answer 7

\[\sqrt{80} = \sqrt{20*4} = 2\sqrt{20} = 2\sqrt{4*5} = 2*2\sqrt{5} = 4\sqrt{5}\]

Answer 8

oh thanks :)

Answer 9

√=20∗4−−−−−√=220−−√=24∗5−−−−√=2∗25√=45√
