Answer:
51
Step-by-step explanation:
11+(-7)^2-9 - original
11+49-9 - square the -7, since its in brackets the negative applies too and a negative x a negative = positive, so it ends up as 7x7+49
60-9 - add both positives 11+49=60
51 - subtract 9 from 60, 60-9=51
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.
