10e3x = 50
First find the exact solution, and then approximate it to 2 decimal digits.
(2V3)Solution
A. log1/354 - log1/32sqrt3
We have to use the following log property
log a - log b= log(a/b)
log1/354 - log1/32sqrt3= log1/3(54/2sqrt3)
= log1/3(1/(3)-5/2)
log ab=b log a
So we get log1/3(1/3)-5/2= -5/2 log1/31/3 = -5/2
b. 10e3x=50
e3x=5
Taking ln on both sides
3x= ln 5
x= ln5/3 ,that\'s the exact solution
x=.54
