Given 0<X , find X
log4x×log564≥log5(x3+x2+x+1)
To solve this problem, we need to compare the expressions log4x×log564 and log5(x3+x2+x+1).
First, calculate log564. We know that 64=43=26. Therefore:
log564=log54log526=2log526log52=3
Next, simplify the left-hand side expression log4x. Using the change of base formula:
log4x=log54log5x
Therefore, the left-hand side becomes:
log54log5x×3=2log523log5x
For the inequality:
2log523log5x≥log5(x3+x2+x+1)
We can now equate the right-hand side:
log5x3/2log52≥log5(x3+x2+x+1)
This implies:
x3/2log52≥x3+x2+x+1
Testing and analyzing this expression results in no valid x satisfying the inequality within real values since exponential growth and polynomial terms do not align. Thus, the inequality cannot be satisfied, and no solution satisfies the given conditions.
Therefore, the solution to the problem is: No solution.
