Discussion Overview

The discussion focuses on the step-by-step breakdown of the expression \((3x)^2\), exploring the rules of exponents and multiplication in algebra. It includes clarifications on how to apply these rules correctly.

Discussion Character

  • Technical explanation

Main Points Raised

  • One participant provides an example, stating that \(3x^2 + (3x)^2\) equals \(12x^2\).
  • Another participant mentions the rule that exponents can be distributed across multiplication, stating \((AB)^2 = A^2B^2\).
  • A different participant explains that \((3x)^2\) represents two factors of \(3x\), which means \(3x\) times \(3x\).
  • Another contribution reiterates the expansion of \((AB)^2\) as \((AB) \cdot (AB) = ABAB = AABB = A^2B^2\).
  • A later reply expresses relief and gratitude for the clarification, indicating a realization of the simplicity of the concept.

for example 3x^2 + (3x)^2 is 12x^2

But i don't remember how to brake down (3x)^2 step by step

You can distribute exponents across multiplication. ##(AB)^2=A^2B^2. ##
 
##(3x)^2## means two factors of 3x; i.e., 3x times 3x.
 
(AB)² = (AB)*(AB) = ABAB = AABB = A²B²
 
Oh my, I had a gut feeling it would be something this simple that I've forgot! haha thanks a lot! ^^
