x = 2.11....? i just ln both #'s in cal...and divided the two to solve for x....ik its wrong but idk how to do this..
do u know the use of ln???
hmm no...
please go through the page http://en.wikipedia.org/wiki/Logarithm
Your problem looms like this..\[7.2^{x} -65=0\] Hence \[7.2^{x}=56\] So take the log of both sides of the equation using your calculator (this will automatically be to base 10) \[\log_{10}7.2^{x} =\log_{10} 65\] Then because of the laws of logorithms you can bring the power down to become the coefficient of the first term \[x \log_{10} 7.2=\log_{10} 56\] Then divide the right by the left leaving x on the left hand side; \[x=\log_{10}56/\log_{10} 7.2\] which equals 2.1146(4.D.P) you can check it equals x by raising 7 to this number - it gives 65.
