how do i calculate sqaure roots in excel
Bernard Liengme - 21 Nov 2007 01:51 GMT
=SQRT(81)
=SQRT(A1)                        best
=A1^(1/2)                           so cube root is  =A1^(1/3)
=POWER(A1,0.5)               worst (to many keystrokes)
best wishes

=25(1/2)  returns 5 as square root

=9*(1/3)   returns 3 as cube root

You could lso use a cell reference if the number was in a cell.

=A1(1/2)

Gord meant ^:

=25^(1/2)
and
=9^(1/3)

And the cube root of 27 is 3.  The cube root of 9 is closer to 2.08...

I think it's time to call it a day<g>

Or maybe just hang up my pool cue.

Oh, wait.  That's a pool queue.

My Excel says 2.080084 -- do I have a bug? :-)

No.

The only bug is my posting incorrect calculations.

I think you missed my smiley. :-)

But when I look again, your calculation was correct. True, it didn't
calculate the cube root, but =9*(1/3) is indeed 3.
