**Steve**, Monday, November 26, 2012 at 11:57pmplug in t=5 and t=1. subtract one from the other. what do you get? you've posted a lot of similar problems. By now you should be getting teh hang of them.

**Steve**, Tuesday, November 27, 2012 at 12:01amummm. what did you do?

s(5) = 5^2 + 5*5 = 50

s(1) = 1^1 + 5*1 = 6

s(5)-s(1) = 44, not 30

**disha**, Tuesday, November 27, 2012 at 12:07ami did it like this

5^2=25 + 5^1= 5 = 30

i guess i did it wrong

**Steve**, Tuesday, November 27, 2012 at 12:11amthat's 5t. not 5^t

5*5 = 25

you did it wrong in two ways. you tried to do 5^2 + 1^2 but did 5^2 + 5^1 instead.

You did not include both terms in your evaluations.

*sigh* review your algebra, if you want to do well in calculus.
