EQUAÇÃO MODULAR - EsPCEx 2021 (Ex. 4 - Mod. F) ~ Matemática Concursos Militares - Nicolas Lazaroto

Hey everyone!! In this video, I solve a math problem from the 2021/2022 EsPCEx exam about Modular Equations! This is the fourth exercise from the 2021 EsPCEx exam, model F. ➡️ A modular equation is one in which there is at least one unknown (x) inside the modulus, like this: Y = |x|. It can also appear outside, but then we enter the different cases and properties of modular equations. ➡️ In mathematics, the modulus or absolute value of a real number 'a' is its absolute numerical value, that is, disregarding its sign. It is associated with the idea of ​​the distance from a point to its origin, that is, its magnitude. This topic is very interesting and recurrent in public service exams, military exams, and university entrance exams!! 💥CONSUMER WEEK AT AMAZON!💥 The Amazon website is offering up to 60% off, so if you want to buy books or any other product at a discount, access this link!! ➡️ https://amzn.to/3KpS5Xf 🔥Want to study with Estratégia Militares or Vestibulares and get a 20% discount on the purchase of any package?
