Answer:
Yes, <em>z</em> will be greater than <em>x.</em>
Step-by-step explanation:
Given expression is
now let <em>y = 2 </em>and <em>x = 1</em>
Then,
where i.e. <em>3 > 1</em>
on simplifying the given expression in terms of y
now suppose if <em>x = 7 and z=3 </em>then,
which gives value of y in terms of negative integer which is not possible according to the given statement since y is a positive integer. Therefore, if y is a positive integer then z will be greater than x.
