OpenStudy (anonymous):

but how do i gett the sq root

OpenStudy (lgbasallote):

if you see a number that repeats twice you can take it out. i.e. \[\sqrt{(2)(2)(3)} = 2\sqrt 3\]

OpenStudy (lgbasallote):

2 repeats so take out 2 from the square root..which leaves 3

OpenStudy (anonymous):

so it eaquals 3

OpenStudy (jkristia):

no it is not = 3, that was just an example

OpenStudy (jkristia):
