simplify the complex rational expressions: show work please √x 1 --- - --- 1 6√x ------------------- √x
First, write the two fractions in the numerator as one, using\[\frac{ a }{ b }+\frac{ c }{ d }=\frac{ ad+bc }{ bd }\](sounds familiar?) So:\[\frac{ \sqrt{x} }{ 1 }-\frac{ 1 }{ 6\sqrt{x} }=\frac{ 6(\sqrt{x} )^2-1}{ 6\sqrt{x} }=\frac{ 6x-1 }{ 6\sqrt{x} }\]Now, instead of dividing by √x, multiply with the inverse:\[\frac{ 6x-1 }{ 6\sqrt{x} }\cdot \frac{ 1 }{ \sqrt{x} }=\frac{ 6x-1 }{ 6(\sqrt{x})^2 }=\frac{ 6x-1 }{ 6x }\]and you're done!
the choices are a) x^2- 1/6x b) (√x/1) - (1/6√x) / √x c) 1-1/6 d) 1-1/6x
Look's like someone answered for you
yep
not correct.
Did you try working it out yourself first? Sometimes answers may not match exactly because they are written in a different form, but essentially mean the same thing.
go to myalgebra.com and type it in... i have a feeling it is D
yes i tried but i had no clue what to do and okay
Peachy, can you show us what you did in your work and we can check where you are stuck on? That way we can guide you in the right direction :)
we? lol abbot your better than me hehe
@blondie16 I believe that you are capable of doing this problem too. I have no doubt in my mind.
lol well than juu hehe
"not correct" is not correct ;) One could take another step:\[\frac{ 6x-1 }{ 6x }=\frac{ 6x }{ 6x }-\frac{ 1 }{ 6x }=...\]But written as as one fraction also has its charm.
