How to solve this hard math problem in the simplest way x to the power of x

If x^x = 81, what is x? 90% of my Grade 12 learners say x=9vbecause 9^2 = 81. That's wrong and I'll prove it. In this video I show you the ONE skill for every x^x problem: x \ln x You will learn: Why you can't guess x=9 or x=3 How to bring x down with \ln How to solve x \ln x = 4.394... by simple trial This is the same method university uses (Lambert W) but I make it SIMPLE for Grade 12. 0:00 The mistake everyone makes 0:35 The ONE skill: x \ln x 2:07 Solving x \ln x = \ln 81 3:13 The real answer x = 3.504.. YOUR TURN: If x^x = 64, what is x? Comment below - I reply to everyone! #grade12maths #maths #algebra #logarithms #exponentialequations
