Just want to check and see if I am setting this up right.
Let y=f(x)=x^26x
Find the average rate of change of y with respect to x in the interval from x=4 to x=5
(5^26*5) (4^26*4)/ 54

yes, if you meant ....
((5^26*5) (4^26*4))/( 54)
notice the difference between the way you typed it, and the way Google, which follows the correct order of operation, interpreted it
http://www.google.ca/#hl=en&xhr=t&q=(5%5E26*5)+(4%5E26*4)/+54&cp=26&pf=p&sclient=psy&safe=off&site=&source=hp&aq=f&aqi=&aql=&oq=(5%5E26*5)+(4%5E26*4)/+54+&pbx=1&bav=on.2,or.r_gc.r_pw.&fp=44e2b71c39a32254&biw=1630&bih=944
compared with
http://www.google.ca/#hl=en&xhr=t&q=((5%5E26*5)+(4%5E26*4))/(+54)&cp=30&pf=p&sclient=psy&safe=off&source=hp&aq=f&aqi=&aql=&oq=((5%5E26*5)+(4%5E26*4))/(+54)+&pbx=1&bav=on.2,or.r_gc.r_pw.&fp=44e2b71c39a32254&biw=1630&bih=944
which is the right way 
Thanks. I am on my ipad and it is such a pain to type this stuff out. I get a little lazy.
