i need to solve this but it's kind of difficult when i try it by myselfe
hope u explain me how u solved than...
First step, combine the like bases:
Now use laws of exponents to take out "like parts". and so
where the value inside the parentheses is a number you can calculate directly. Do the same thing on the right so you get something like where "A" and "B" are specific numbers. Finally, take logarithms of both sides.
Added: the "A" and "B" are which, according to my calculator is 1.8900 (to four decimal places) and [tex]B= 3^{-1/2}- 3^{-3/2}= 0.3849.
Your equation is taking logarithms of both sides, log(1.8900)+ (log(2)/3)x= log(0.3849)+ (log(3)/2)x. You can use either common or natural logarithms and get the correct answer.
actually i still cant get this...i'm new to exponential equations...i thought u will go to the end of this task...and we didnt learned logarithms, but i just readed some lessons in internet about logarithms...anyway thanks i will keep practising and practising over over again ...probably be like you in math i hope soo ...
