AI Thread Summary
The discussion focuses on solving the simultaneous equations 2log_2y = log_43 + log_2x and 3^y = 9^x. The transformation of 3^y into (3^2)^x leads to the conclusion that y = 2x. Further simplification using logarithmic properties results in log_2x = log_2(√3/4). Participants emphasize the importance of applying logarithmic identities to find the values of x and y, indicating a collaborative effort to clarify the solution process. The conversation highlights the utility of logarithms in solving complex equations.

Homework Statement


Solve the simultanious equations
2log_2y = log_43 + log_2x
3^y = 9^x

The Attempt at a Solution


3^y = (3^2)^x
y = 2x

2log_2 x + 2log_2 2 = log_2 \sqrt{3} + log_2 x
log_2 x = log_2 \frac{\sqrt{3}}{4}


No idea what to do from where, what does x equals?

Correct up to now.
The only steps that remain to be done is to use

2log(...) = log[(...)^{2}] and

logu + logv = log (uv)
 
If logax = logay, then x = y.
 
Ah okay, thank you guys.
