Question

Can someone please help with this?x^-1+10x^-2+25x^-3

Answer 1

You mean you have this form: \[\frac{ 1 }{ x }+\frac{ 10 }{ x^2 }+\frac{ 25 }{ x^3 }\]
What are you supposed to do with it? Write it as one fraction?

Answer 2

(x^2/x^3)+(10x/x^3)+(25+x^3)

Answer 3

(x^2+10x+25/x^3)

Answer 4

\[(x+5)^2/x^3\]

Answer 5

Well, if writing it as one fraction was what you were supposed to do, then madscientist101 has answered your question...

Answer 6

I'm assuming it's simplification, however, ZeHanz is right, you need to tell us what to do with it.

Answer 7

Its factoring with negative exponents the answer is (x+5)^2/x^3 but not sure how to get there

Answer 8

Bro, @madscientist pretty much posted the solution for you
