Answer:
The statement is false.
Step-by-step explanation:
Let a and b represent two odd integers.
The average (A) is defined by:
A=
In order to prove the statement, you have to show that it's true for all odd integers. But, to disprove it, you just have to find a counterexample where the statement is false.
Notice that it is easier to try to find a counterexample.
For example, a=3 and b=5
A=
The result of the average is even, therefore the statement is false.
The previous calculation is a counterexample.
Given:
A number is
To find:
The scientific notation of the given number.
Solution:
Scientific notation of a number is the product of a number between 1 to 10 and 10 to the power some integer.
We have,
It can be written as
Therefore, the scientific notation of the given number is .
