Need Help!!

Answer 1

u r right

plug h= 4

Answer 2

This step is a little sloppy,\[\large\rm \lim_{h\to0}\frac{h}{h \sqrt{4+h}+\sqrt4}\]
you should use brackets\[\large\rm \lim_{h\to0}\frac{h}{h( \sqrt{4+h}+\sqrt4)}\]and then dividing out is fine

Answer 3

sorry h=0

Answer 4

\[\frac{ 1 }{ \sqrt{4}+\sqrt{4}}\]
