## anonymous 5 years ago solve this equation for x 4^x =30

1. anonymous

$x=\log_{4} 30$ after I cant remember how to deal with

2. anonymous

after that

$4^x = 30 \implies ln 4^x = ln 30 \implies x ln 4 = ln 30 \implies x = \frac{ln 30}{ln 4}$

ttt is also correct. $$\frac{ln 30}{ln 4} = log_4 30$$
