the population will reach 8 billion by 2012 ,as calculated by properties of logarithm.
<h3>What is Logarithm?</h3>
- The opposite of exponentiation is the logarithm.
- This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.
- A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.
Given:
- y = 6.72 (
), where
- y = population in billions
- x = time in years
To find: Year when population is 8 billion, i.e., y = 8.
Finding:
8 = 6.72 (
)
=> 
Taking log on both sides
=> 
=> log(1.19) = x (log 1.014) (as
)
=>
= x
=> x = 
=> x = 12.58
Hence, the population will reach 8 billion by 2012 ,as calculated by properties of logarithm.

Answer:
9p−18
Step-by-step explanation:
Expand by distributing terms
(−9×2 ) (−9×−p)
Simplify
−18−9×−p
Regroup terms
−18−(−9p)
Remove parentheses
9p−18
