I think I may be missing something ... I don't completely understand your question.
All you need to make a fraction is two numbers and a bar. The bar can be either
horizontal or slanty. Then you write one number on top and the other number on
the bottom, and bada-bing, you have a fraction.
You can make fractions like
2700 / 600
27 / 6
9 / 2 (all 3 of these have the same value)
600 / 2700
6 / 27
2 / 9 (all 3 of these have the same value)
F(x) = ㏑(x² - 4)
Domain: {-2 ≤ x ≤ 2}, or [-2, 2]
Answer:
As there is one math problem over there.
Lets see the question first:
It says that "A hair dryer is rated
,if you use the dryer for
.How much electric energy do you use ?"
Final answer = Electic energy 
Step-by-step explanation:
Electrical Energy
.
The total amount of electrical energy used depends on the total power used by the electrical device and the total time they are used for.
So we have been given the power of the hair dryer 
Now the time it has been use for 
To calculate electric energy we will multiply both the terms.
Electric energy 
So electric energy used for the hairdryer is =
