The idea is to factor the radicand into two factors where one factor is a perfect square (the largest perfect square possible)

Then you break up the root and simplify

\[\Large \sqrt{54} = \sqrt{9*6}\] \[\Large \sqrt{54} = \sqrt{9}*\sqrt{6}\] \[\Large \sqrt{54} = 3\sqrt{6}\]

So \[\sqrt{60}= 3\sqrt{10}\]
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
keep in mind that 60 = 4*15

So I am looking for the biggest possible number to go into it? Like \[\sqrt{64} = 2\sqrt{16}\]
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
64 is a perfect square
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
since 8^2 = 64 or 8*8 = 64
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
so \[\Large \sqrt{64} = 8\]

\[\sqrt{72}= 2\sqrt{18}\]
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
find the largest perfect square that is a factor of 72
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
the perfect squares (up to 100) are: 1,4,9,16,25,36,49,64,81,100

HorseCrazyGirlForeverBest ResponseYou've already chosen the best response.1
So I have to use a perfect square every time?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
yes, you have to factor the number into two numbers where one number is the largest perfect square possible
