Evaluate the following expressions. Show your work.
4.
log(base 3)18
log%283%2C18%29
apply "change of base":
log%2818%29%2Flog%283%29
2.631
.
Solve the following logarithmic equations. Show your work.
6.
log(base x)16 = 4
log%28x%2C16%29+=+4
16+=+x%5E4
16%5E%281%2F4%29+=+x
%284%5E2%29%5E%281%2F4%29+=+x
4%5E%282%2F4%29+=+x
4%5E%281%2F2%29+=+x
2+=+x
.
7.
log(base d)12 = 6
log%28d%2C12%29+=+6
12+=+d%5E6
12%5E%281%2F6%29+=+d
1.513+=+d
