Simplify
(5x^-2)-(3y^-1)
---------------
(x^-1)+(y^-1)
(1)
-------------
25x^2 + 22xy - 3y
I get (5x^-1)-3!
I do not understand how you arrived @ this answer. Can you please explain. Thank you
sure! :)
remember that we can add/subtract exponents just like normal numbers.
First put everything in the numerator and then add up all the exponents.
(5x^-2)-(3y^-1)
---------------
(x^-1)+(y^-1)
(5x^-2)+(x^1)-(3y^-1)+(y^1)
now add: (5x^-1)-3
x^=-2+1=-1
y^=-1+1=0 or goes away
Does this help?
There is no division here? Is this all adding and subtracting?
I thought there was division too. So what is the final answer?
you can do it by division or add/subtract. I did it by add/substract because its easier.
First you put all the terms in the numerator. Then you combine terms and add/substract exponents to get your answer.
Follow the steps above and you will see the answer.
Do you get it now?
