Addition and Subtraction:
Example: 2x102 +10-1-0.3x101=(2x100)+(1x0.1)-(0.3x10)=200+.01-3=197.1
Multiplication: 10a.10b=10a+b
Example: 102.103=105 ; (2x10-3).(4x102) = 8x 10-3+2 = 8x10-1 = 0.8

Logarithms
Definition: N = ax ; x = logaN
for a = e = 2.71828; N = ex ; x = ln N (natural logarithm)
for a = 10 ; N = 10x ; x = log10 N = log N (logarithm base 10)
Addition and Subtraction:
Example: log (3) + log (2) = 0.477 + 0.301 = 0.778
Multiplication: log (a.b) = log a + log b
Example: log 6 = log (3x2) = log 3 + log 2 = 0.477 + 0.301 = 0.778
Division: log (a/b) = log a - log b
Example: log (1.5) = log (3/2) = log 3 - log 2 =0.477 - .0301 = 0.176
Power: log (a)b = b. log(a)
Example: log (100.3) = 0.3 log (10)=0.3x1 = 0.3 ; log (5-2) = -2 log (5) = -1.398

Exponential Expiration Time
Appendix C
One of the pressing questions of our time is that for how long our
nonrenewable resources last. When a quantity such as the rate
of consumption of a resource is growing at a fixed percentage
rate, r, after time t we have:
..ERT
(C.1)
where;
N0 is the initial rate of consumption per year (t = 0),
N is the rate of consumption per year at a later time, and
r is the annual growth rate
The consumption rate will grow to twice the initial value (N/N0
= 2) after time
LN 4
R
R
2
(C.2)
where R is the percentage growth per year (R = 100.r)
The cumulative consumption of the resource between the present
time t = 0 and time t = T in the future is:
1
4
° .T DT . R 4
E Ÿ R
(C.3)
We can rearrange this equation to give the exponential expiration
time, i.e. time it takes for the resource to be depleted.
%%4 R LNR1 . (C.4)
In this equation, Q represents the ultimate size of the resource
(given in barrels of oil, tons of coal, etc.), N0 is the consumption
rate (given in barrels of oil per year, tons of coal per day, etc.)at
time t = 0.
Example C-1: The US energy consumption increased from
76.8 quads in 1984 to 100.4 quads in 2004 (See Table 1-3).
Assuming that the consumption followed an exponential
growth pattern, find
a. The annual growth rate,
b. The doubling-time,
c. Total US energy consumption during this period.
501
Solution: Substituting into Equations C-1 through C-3, we
will have:
a. 100.4 = 76.8 e 20r; or
r = 1/20 ln (100.4/76.8) = 0.013 (1.3% per year)
b. T2 = 70/1.3 = 52.2 years
c. Q = 76.8/0.013 (e0.013x20-1) = 1,754 quads
Example C-2: The total world petroleum endowment (that
already produced and that will remain to be exploited) is
estimated at 3,563 billion barrels (See Table 7-3). The same
data indicates the cumulative production of 708 billion
barrels and proven (remaining) reserves of 2,855 billion
barrels. Assuming that the oil consumption was at 98.9
million barrels a day in 2000, calculate the remaining life
expectancy (exponential expiration time) of the world’s
petroleum reserves.
Solution: Substituting for the total size of remaining
reserves (Q = 2,855 bbo), the annual consumption rate of
N0 = 98.9x106x365 = 36.1x109 barrels/year (36.1 bbo/year) at
the turn of the century, the exponential expiration time is
calculated for different rate of consumption growth as:
