Question 1066217

Hi, 

I am being introduced to algebra and I don't understand how to simplify the following.

X^-3 + X^-2 
-------------
          X
<pre>If {{{(x^(- 3) + x^(- 2))/x}}}, then the correct way to simplify it is:
{{{(1/x^3 + 1/x^2)/x}}}
We SEPARATE the expression to get: {{{(1/x^3 + 1/x^2)}}}{{{"÷"}}}{{{x/1}}}
{{{(1 + x)/x^3)}}}{{{"÷"}}}{{{x/1}}} ------ Multiplying left expression by LCD, {{{x^3}}}
{{{(1 + x)/x^3}}}{{{"*"}}}{{{1/x}}}------- Applying KEEP, CHANGE, FLIP
{{{highlight_green(matrix(1,5, (1 + x)/x^4, or, 1/x^4 + 1/x^3, or, x^(- 4) + x^(- 3)))}}}
