\[f(x) = x^2\log_{2} (x^2+1)\]
the log2 is best viewed as ln(x^2+1)/ln(2)
since 1/ln(2) is a constant, all thats left is to consider this as a usual ln(u) type issue

I understand to start by converting the log base 2 into a natural ln base e, which leads to: \[f(x)=x^2(\ln (x^2 + 1) /\ln 2)\] I am unsure how to address the fractional term involving the ln's.
1/ln(2) is a constant; nothing changes about it ... so
remove it, stick it to the side, put a stick note on top ot it and work the rest of the problem
Ah, the 1/ln2 is a constant. Good insight. Thank you, @amistre64.
what is a stick note?
sticky note is what thats spose to be, a post it note, something to remind you not to forget about it in the end :)
okay, got it.
I think the key to this one for me was recognizing that constant.
yep
Would I then use the product rule against the remaining terms x^2 and ln(x^2+1) ?
i would, seeing how its a product ;)
Sometimes all the new stuff to learn can create uncertainty of the obvious.
yeah, im dong that with existence and uniquenes thrms right now wondering what gppd to do and stuff
good to do and stuff ... cant type
What class are you taking at this time?
im in college going to take linear algebra, calc3, and diffy qs in the spring
