x=log196  y=log225 z=log256

 Express the following in terms of x, y, and/or z

1.  Log2
256 = 2^8
log(2) = z/8
-------
2.  Log3
log(9) = log(900) - log(100) = log(900) - 2
900 = 225*4
log(900) = y + z/4
log(9) = y + z/4 - 2
{{{log(3) = y/2 + z/8 - 1}}}
--------
3.  Log5
{{{log(5) = log(10) - log(2) = 1 - z/8}}}
-------
4.  Log7
196 = 2^2*7^2
log(196) = 2log(2) + 2log(7)
x = z/4 + 2log(7)
{{{log(7) = (x - z/4)/2 = x/2 - z/8}}}
--------
5.  Log10
log(10) = 1</PRE>
