Question 254405
Never heard of fractional exop onents!
Have you?
You might get a better response if you check your spelling.
It is just laziness, arrogance and disrespect since all computers have spell checking.
You need to learn. We are teachers here. Ask the question properly.
Not only did you misspell the last word but you used is with a plural noun. 
I give you 5 points for a question mark but take it away for the small letter starting the sentence.
If you want us to take you seriously you should take us seriously.
