Simplify by factoring..... equation on bottom

OpenStudy (anonymous):

\[\sqrt{20}\]

jimthompson5910 (jim_thompson5910):

The list of perfect squares are 1, 4, 9, 16, 25, ....

jimthompson5910 (jim_thompson5910):

which perfect square is the largest factor of 20?

OpenStudy (anonymous):

4?@jim_thompson5910

jimthompson5910 (jim_thompson5910):

yes

jimthompson5910 (jim_thompson5910):

so 20 = 4*5

jimthompson5910 (jim_thompson5910):

making \[\large \sqrt{20}=\sqrt{4*5}\]

OpenStudy (anonymous):

i thought it was suppose to look something like this? \[4\sqrt{5}\]

OpenStudy (anonymous):

@jim_thompson5910

jimthompson5910 (jim_thompson5910):

well it's not the final answer of course

jimthompson5910 (jim_thompson5910):

you would then break up the root to get \[\large \sqrt{20}=\sqrt{4}*\sqrt{5}\]

jimthompson5910 (jim_thompson5910):

I'm sure you see what to do from there

OpenStudy (anonymous):

\[4\sqrt{5}\] so the answer i put was right? @jim_thompson5910

jimthompson5910 (jim_thompson5910):

the square root of 4 is _____

OpenStudy (anonymous):

2 so its \[2\sqrt{5}\] @jim_thompson5910

jimthompson5910 (jim_thompson5910):

good, \[\large \sqrt{20}=2\sqrt{5}\]

OpenStudy (anonymous):

ya thank you @jim_thompson5910
