Can someone help me?

#

Hi guys

#

I need help with my answers and idk if I'm right

#

These are the questions

#

#

and these are my questions

#

#

sorry if it is not in order.

#

but these are my answers in 10-15

Dude you seriously need to work on your algebra

The way you solve this limit is noticing that it’s the same as $\frac{d}{dx}x^4$ at x=1

A.k.a. 4x^3

#

Then when x=1 4(1)^3

#

=4

#

$(1+h)^4 \neq 1+4h+h^4\(1+h)^4 = 1+4h^3+6h^2+4h+h^4$

Dude, if he's learning limits he doesn't know derivatives yet.

#

Also, you can't solve the limit by noticing it's the derivative because the derivative is the limit. It's circular reasoning.

#

Not really if you know the power rule works

#

Also the question seems set up specifically so that you could solve it that way

#

Which makes me think he’s been taught derivatives a little

When you use the power rule, or any theorem for that matter, you're just invoking a shorthand form of the proof of that theorem.

I think i already did the right solution in number 11,12,13
