What is the simplified form of √140?

OpenStudy (domebotnos):

First find a perfect square in 140. 4*35 would work

OpenStudy (domebotnos):

2*2 = 4 so you take 2 out

OpenStudy (domebotnos):

There is no perfect square in 35 and the answer is 2√35

OpenStudy (anonymous):

sqrt140 Pull all perfect square roots out from under the radical. In this case, remove the 2 because it is a perfect square. 2⋅sqrt35 Multiply 2 by sqrt35 to get 2sqrt35. 2sqrt35
