Exponential inequalities
Hi there, it's Aries here ;-)
I was checking some exponential function inequalities: solve(3root(2^(4*x-1))>=(2^(x-5))/(4root(16^x))), the calculator reboots. Typing solve(2^((4*x-1)/3)>=(2^(x-5))/(16^(x/4))), all is ok, the calculator returns the correct answer (x>=(-7/2)). Another example: solve(2^(3*x-1)+2^(6*x-2)-2^(3*x+3)<(4^(3*x-2))), the calculator gives the advise "Warning, solving parametric inequation requires assumption on parameters otherwise solutions may be missed. The solutions are UNABLE TO ISOLATE x IN..... Why happens this ? Is it due to some sort of complexity or what ? Is there a "workaround" to solve this kind of inequations ? Thanks all for the explanations, Aries ;-) |
