SUMMARY

The equation log(x)/log(4) = (2^x) - 6 cannot be solved using elementary functions due to the presence of the variable x both inside and outside of transcendental functions. The discussion highlights that the Lambert W function may be a viable method for solving such equations, as it is specifically designed to handle equations of the form x * e^x = y. This advanced mathematical concept is essential for finding solutions to complex equations involving logarithmic and exponential functions.

PREREQUISITES
  • Understanding of logarithmic functions and properties
  • Familiarity with exponential functions, particularly base 2
  • Knowledge of the Lambert W function and its applications

without using the graphing calculator to find the intersect
is it possible to solve this?
i tried this solve this equation a long time, i still can't solve for x...
log(x)/log(4)=(2^x)-6

Generally speaking, a function having the unknown x both inside and outside transcendental function- and here ex is the inverse of ln(x) so ex is "doubly" outside ln(x)!- with elementary functions. You might be able solve it using "Lambert's W function" which is defined as the inverse f(x)= xex. That is, W(xex)= x.
 
is this university stuff?
cuz i just started learning log
