Question

Ajutati-ma!!!!
lim(x tinde la 3) (3^x-27)/x-3=???? Multumesc!!!!

Answer 1

pai (x tinde la 27)/27-3=×=>n^x Gata!

Answer 2

daca limita este asa : $\lim_{x \to \3} \frac{ x^{3}-27 }{x-3}$ =$\lim_{x\to \3} \frac{(x-3)(x^{2}+3x)+9}{x-3}$ ; simplifici cu (x-3) si ramane $\lim_{x \to \ 3} {x^{2}+3x+9}=27$
