Como economista, neste vídeo em específico, sou suspeito para dizer que foi um ótimo exemplo aplicado. Parabéns pelo excelente trabalho, professora Juliana. Abraços de Recife-PE.
Are there calculator engines that can take logarithm bases of decimal expansion? - at least this is a finite decimal expansion so it can be put as a rational number after some painful prime factorization - would you be looking at the binomial expansion of 1.01 - =(1+0.01)^(4n). Unfortunately since you are solving for n I guess you have to make the expansion and then look at only a certain number of terms before stopping?
I'm not sure I understand the question. Yes, you could use binomial expansion to find successive approximations to the equation, first you do 1.5 = 1 + 4n*0.01, then the next one you do 1.5 = 1 + 4n*0.01 + (4n choose 2)*0.0001, but I don't think I'd go beyond that because I don't want to solve a cubic equation by hand. And if I'm using a calculator, might as well just ask it for log_{1.01}(1.5) instead of asking it to solve a sequence of polynomials of higher and higher degree. Could be the beginnings of a Paper 3 question, though :-)
Hi Juliana! Please make videos in Portuguese. The people don't know Mathematics or English. In this way, the probability of any particular person attending is greatly diminished.
I do make videos in Portuguese too :-) I also think that more people in the world know English than Portuguese, so, by this logic, it actually increases the probability.

JULIANA YOU JUST SAVED MY EXAMS THANKS
one of the best explanations of time value of money
Oh my God I really love your studying style and I subscribed to your channel keep going !!!
Keep going! Esse canal vai bombar! Sensacional.

Heyy Do you make any chemistry video yet .I love your teaching style so plz let me know if you have chemistry one!!!
🥺🙂
Wonderful.
Really nice!
