May ask for someone to explain this? The problem is in the comment.

I know the sqrt of 16 is 4, I just don't understand why it's .4 and not 0.04.

OpenStudy (alexandervonhumboldt2):

0.4*0.4=4/10*4/10=16/100=0.16

OpenStudy (anonymous):

Ah, I see. Thanks.

OpenStudy (alexandervonhumboldt2):

0.04*0.04=4/100*4/100=16/10000=0.0016
