Why no amount here?
Hey, I just don't understand why the result is 3a and not 3|a|. You can substitute – and + for a in the square root of 9 a to the power of 2, so why without absolute values? It would be nice if someone could explain.

Hi, how does this work with these strange numbers? I'm good at math. It's 9b
Each carton with 12 bottles containing 200ml costs 19€ But I need a total of 50 liters. What do I need to calculate? I have no idea.
Good evening, Unfortunately, I don't yet fully understand the solution to the problem, and I would really appreciate your helpful explanations. It's about problem 1.6.
I've already started a bit but I don't know if it's right and how it continues Thank you
I may be autistic and only like round numbers with zeros after the first digit, preferably after a 1. Other numbers give me a headache because I find them messy and chaotic. And then I also like "infinity."
Aus dem Term
ganz links, folgt schon die Bedingung
und daher kannst Du am Ende den Betrag auch weglassen.
Es gibt eine alternative Rechnung:
sqrt(3a)*sqrt(3a)=3a^0.5*3a^0.5=(2a)^(0.5+0.5)=(3a)^1
sqrt(x) ist die Quadratwurzel von x.
Weil du a ja erst quadrierst, bevor du die Wurzel ziehst. Da ist es egal ob es vorher als a negativ war, danach ist es positiv und eine Wurzel kann gezogen werden.
Negative a kannst du nicht auf der Linken Seite der Gleichung einsetzen, da nur Wurzeln von positiven Zahlen existieren.
