SOLUTION: In the problem c= 17(2) + 19(2) It comes out to c= 289+361 And that equals c= 650 or 25.5 Where did the 25.5 come from? How do I find that

What is this?
----------------------
c= 17(2) + 19(2)
---------------------


If you mean this, then write the exponents as they should be:
c=17^2+19^2
c=17%5E2%2B19%5E2

You already know how to add two plain numbers:
289%2B361=650


The 25.5 does not come from anything - or maybe from a different problem exercise.

You didn't write the problem correctly; and the other tutor didn't recognize what problem you were TRYING to work.

The problem is about the Pythagorean Theorem; so the statement of the problem should talk about c^2 -- not just c.

c%5E2+=+17%5E2+%2B+19%5E2
c%5E2+=+289%2B361+=+650
c+=+sqrt%28650%29+=+25.5 rounded to the nearest tenth.
