simplest form of 8 / s + 8 / s2

[dkarolasz]

8 8
___+____
s s2

I would start doing

8(s2) 8(s)
_____+______
s s2

8s2 8s
_____+_______
s s2

I know I have to add the top

so I think it would be 16s3
______
s+s2

but that doesn't look right

to add two fractions, you need a common denominator ...

8/s + 8/s² =

the common denominator of these two fractions is s² ...

8s/s² + 8/s² =

... finish up.

8s/s2 + 8/s2 =

16s/s2= simplest form would be 16/s

 

[skeeter]

no ... that is incorrect.

I can't add them together because there not the same, so I would just bring them over.

8s+8/s2

8s + 8 is NOT 16s

Pleaase back up. Reread the last section or two and give it all another go.

8s+8/s2

put a set of parenthesis around the terms in the numerator, and indicate that the 2 after the s is an exponent, and you're all done.

(8s+8)/s^2
