Simplify. (Help Needed)

[RicanGurl]

b-1 + c -1 =


(the -1 are exponents)

You mean b^-1 + c^-1? Well not much you can do besides combining it into one fraction. Is that what you're looking for? Well, remind yourself of what it means when we say b^-1.

 

[RicanGurl]

Yeah that is what I mean.

1/b + 1/c ? is that the end of the simplification?

 

[o_O]

Do you know how do you add fractions? You need a common denominator now and just add.

 

[RicanGurl]

uhmm

1/b + 1/c = 2/ bc ?

 

[skeeter]

no ...

1/b + 1/c = c/(bc) + b/(bc) = (b + c)/(bc)

 

[RicanGurl]

So thats the answer?

the answer cant be~

c/b

b/c
