There is no way to use methods of algebra to solve an equation for
an unknown that appears both inside and outside of a logarithmic,
exponential, or trigonometric function. The only way is to
approximate it with a computer, calculator, or iterative method
("educated" trial and error).
Perhaps you did not mean to have " x= " in the front as if it were
part of the equation, and meant only this equation:
  
Let's convert one of the logs so we will have both logs to the same
base.
I choose to convert  to base 2.
You should memorize the change of base formula:
and plug in a=x, b=8, c=2
 
So substitute  for in
Multiply through by 3
 
 
By the definition of logarithms, from the above equation,
we have this:
 
(You fill in those blanks, the first one with an
eponential expression and the second with a number.

In general, to convert a number n in base 10 to another base b, repeatedly divide n by b and pick off the remainders, until the number left is 0.
To convert 26 base 10 to base 2...
26/2=13 remainder 0
13/2 = 6 remainder 1
6/2 = 3 remainder 0
3/2 = 1 remainder 1
1/2 = 0 remainder 1
Those remainders, written in reverse order, are the digits of the converted number in base 2.
ANSWER: 26 (base 10) = 11010 (base 2)
Here is another random example to help you understand the process: convert 417 base 10 to base 5:
417/5 = 83 remainder 2
83/5 = 16 remainder 3
16/5 = 3 remainder 1
3/5 = 0 remainder 3
ANSWER: 417 (base 10) = 3132 (base 5)
CHECK: 3132 (base 5) = 3(5^3)+1(5^2)+3(5^1)+2(5^0)=3(125)+1(25)+3(5)+2=375+25+15+2=417

Question 42221: Which of of numbers are opposites?
A) x and x^-1
B) 2 and -2
C)12 and 21
D) 2 and 1/2
Answer by CoolRekt(53) (Show Source):
You can put this solution on YOUR website! Choice B is correct. It's like changing something to a negative. A is wrong since it just changes the exponent, not the base. C is wrong since it just swaps the numbers backwards, not making it a negative. D is wrong because 2 cannot be opposites of a fraction (especially if it isn't a negative).
