In short it's ALT + 251 (note, no preceding zero)

Unicode it is U-221A

√

If that doesn't work then:

Press and hold down the Alt key.
Press the + (plus) key on the numeric keypad.
Type the hexidecimal unicode value (221A).
Release the Alt key.

	I am getting û for Alt 251 – ajy Oct 12 '11 at 2:04
	alt-251 is font dependent, so use the unicode sequence alt+221a as above - this will only work in unicode aware apps. Note you can use charmap in most versions of Windows to work out either the alt sequence or alt-unicode sequence. – Paul Oct 12 '11 at 2:31
	doesn't work. I am using an apple keyboard on a windows machine. Could that be a problem? – ajy Oct 12 '11 at 4:08
