Since b is a variable ( unknown) we replace b with 8 since its given to us so the equation turns to 8-3-3 which we do 8-3=5-3=2
Answer:

Step-by-step explanation:
Given:
The expression to simplify is given as:

In order to simplify this, we have to use the law of indices.
1. 
So, 
Substitute this value in the above expression. This gives,

Now, we use another law of indices.
2. 
So, 
Substitute these values in the above expression. This gives,

Finally, we further simplify it using the law 
So, 
Therefore, the given expression is simplified as:

The book value at the end of year 2 of the equipment depreciated using the sum-of-the-years’-digits method is $65,560.
<h3>What is the book value at the end of year 2? </h3>
Depreciation is a method used to expense the cost of an asset. Book value is the cost of the asset less the accumulated depreciation.
Sum-of-the-year digits = (remaining useful life / sum of the years ) x (Cost of asset - Salvage value)
Depreciation expense in year 1:
Sum of the years = 1 +2 +3 +4 + 5 + 6 + 7 + 8 + 9 + 10+ 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 = 210
Undepreciated life of the asset = 20
(20 / 210) x ($79,600 - 4,000) = 7200
Depreciation expense in year 2:
19 / 210 x ($79,600 - 4,000) = 6840
Book value = 79600 - 7200 - 6840 = $65,560

Step-by-step explanation:
To find irrational number between any two numbers, we first need to understand what a rational and irrational number is.
Rational number is any number that can be expressed in fraction of form
. Since q can be 1, all numbers that terminate are rational numbers. Example: 1, 12.34, 123.66663
Irrational number on the other hand can't be expressed as a fraction and do not terminate. Also, there is no pattern in numbers i.e. there is no repetition in numbers after the decimal point.
For example: 3.44444..... can be expressed as rational number 3.45.
But 3.414114111.... is an irrational number as there no pattern observed. Also,it does not terminate.
We can find infinite number of irrational numbers in between two rational numbers.
<u>Irrational numbers in between 0.3 and 0.7:</u>
0.3101001000......
0.410100100010000....
0.51010010001.......
0.6101001000....
There are many others. We can choose any two as answers.
Ok so you would just take the two fractions and simply if needed and that the answer!
