Question 238434: I tried everything and seem to never get the answer.
Log(base 2)1/4 - log(base 3)1/81 = log(base 7)x
Answer by edjones(8007) (Show Source): You can put this solution on YOUR website!
Log(base 2)1/4 - log(base 3)1/81 = log(base 7)x
log[7](1/4)/log[7](2) - log[7](1/81)/log[7](3) Change the bases to base 7
=-2 -( -4) = 2
2=log[7](x)
7^2=7^log[7}(x)
x=49
