Scientific notation is used so that the order of the number is known in first glance. The value of the given number in scientific notation is given by: Option B:
<h3>How does scientific notations work?</h3>
The number is written in the form where we have
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
- Better readability due to compact representation
- Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.
For the given case, the number in consideration is 0.0000069
Rewriting it in fraction form, we get:
(we used two facts: first that :
and second that:
Thus, the value of the given number in scientific notation is given by: Option B:

Answer:
The number of each kind of apartment in the building is 130 .
Step-by-step explanation:
Given as :
The total number of floor in a building = 15
The number of apartment on each floor = 26
So, The total number of apartment = 26 × 15 = 390
The number of kinds of apartment in the building is 3 , i.e 1-bedroom , 2-bedroom , 3-bedroom
Let The number of each kind of apartment in building = x
So, According to question
The number of each kind of building =
or, x =
∴ x = 130
Hence The number of each kind of apartment in the building is 130 . Answer
Answer:
<u>2.256 x 10 to the power of 25</u>
Step-by-step explanation:
There are 3.76 x 10 to the power of 22 atoms in 1 gram of oxygen
So, there are x atoms in 600 grams of oxygen
Using the ratio and proportional
So, the number of atoms = 600 * 3.76 x 10 to the power of 22 =
So, the answer in scientific notation as A.BCD x 10 to the power of E
Will be <u>2.256 x 10 to the power of 25</u>
