1. ECUACIONES EXPONENCIALES Y LOGARITMICAS
1. 2logx – log4x = 2
2. log(x2
– 4x + 3) = log(3 – 2x)
3. log(x – 2) + 1 = log(x – 1) + log2
4. 3logx – log32 = logx – log2
5. logx + log50 = 3
6. log(3x + 1)1/2
– log(2x – 1)1/2
= 1 – log5
7. logx = 1 + log(22 – x)
8. log2 + log(x – 3) = log
9. 2logx = 3 + log(x/10)
10. log2 + log( 11 – x2
) = 2log(5 – x)
11. 2log2X – log2(X – 16) = log24
12. 2log(5x + 4) – log4 = log(x + 4)
13. log[ + 2] – log(2x – 5) = 0
14. log( x + 5) – 1 = log( x – 4)
15. log( x + 1) + log(x – 3) = logx2
