#### Answer:

#### Explanation:

**Log of #445.66#**

In the log table, find the row for numbers beginning

They will contain numbers like

Then since

Hence the logarithm of

Then:

#log(445.66) = log(100*4.4566)#

#= log(100)+log(4.4566) ~~ 2+0.6490 = 2.6490#

**Antilog of #445.66#**

In the antilog table against

That tells us that

Hence:

#10^445.66 ~~ 4.571 xx 10^445#
