Question 1192803
<br>
The common ratio is the second term divided by the first term:<br>
{{{ln(x^8)/ln(x^16)}}}
{{{ln(x^8)/ln((x^8)^2)}}}
{{{ln(x^8)/(2*ln(x^8))=1/2}}}<br>
The common ratio is 1/2.<br>
By the way....  The comment from the other tutor that the "for x>0" is not needed in the problem is incorrect.  The sequence is<br>
ln(x^16), ln(x^8), ln(x^4), ln(x^2), ln(x), ln(x^(1/2)), ln(x^(1/4)),...<br>
x>0 <b><i>IS</b></i> required for this sequence, starting with the 5th term, ln(x).<br>
