**drwls**, Wednesday, November 12, 2008 at 5:38pmYour calculator is wrong.

Enter 4, then press the "change of sign" button (if you have one) to get -4 in the display, and then hit x^2.

If you still get -16, get a better calculator , or call them for tech help. I hope you saved your receipt.

sqrt 40 = sqrt (4*10) = 2 sqrt 10

This has nothing to do with GCF's
