How do you solve for x 4to the 5x+1=16 to 2x-1?
==========================================================
100^(2x+3) = 1000^(x+5)
Taking the log (base 10) of both sides gives:
(2x+3)log(100) = (x+5)log(000)
(2x+3)2 = (x+5)3
Solve for x:
4x+6 = 3x+15
This gives x = 9
The 2nd problem is solved the same way, but use log base 4
