5(0.10)^x = 4(0.12)^x... x = ? getting aggravated
5(0.10)^x = 4(0.12)^x
this problem is driving me nuts. i graphed it and got x~1.2239011 but I can't find it on paper.
i have been using the property ln(a^x) = x*ln(a)
i tried doing x*ln(0.50) = x*ln(0.48)
but i still can't get it. it is making me crazy. i thought i was good at math :(
every time i try to solve it, my x's disappear. i always end up dividing ax/bx and losing them. it is driving me absolutely crazy. is there a different property i should be using? I'm almost positive that all i should need is ln(a^x) = x*ln(a)
