"show by solving the following log equation that the exact value of x can be written in the form 4p root p and write down the value of p.

log to the base x (2x) + 2log to the base x of 8 =3"

I started by doing:
log to the base x (2x *64) = 3
log to the base x (128x) = 3

and after that im not really sure... any help appreciated

Bit of a starter for you;

logx2x + logx8 = 3

so, by the logxa + logxb = logxab, ( http://www.hsn.uk.net/files/HSN23300.pdf , page 4 [136] )

logx2x + logx8 = 3
is equivalent to logx16x = 3
