Question

solve: log4(x+1) + log4(x-1) = 6. I'm not sure how to get the 6 to a log4 base... thanks!

Answer 1

first look at some rules for log\[\huge\rm \log ~x + \log~ y = \log (x \times y)\]
\[\large\rm log ~x - \log~ y = \log \frac{ x }{ y }\]
so there is plus sign how would you change that ??

Answer 2

log4[(X+1)(x-1)] = 6 ? it's the 6 that's throwing me off..

Answer 3

haha okay you have to change logarithmic to exponential form

Answer 4

right side number become exponent of base
and move left side number to the right side like tin this example
