Question 303060
If I understand you correctly, we are looking at:
{{{ (10a^9/2) / (9a^4/6) }}} <br>
In standard notation it would be: (10a^9/2) / (9a^4/6) 
Is that correct? <br>

If so:
*[invoke explain_simplification "(10a^9/2) / (9a^4/6)"] 
{{{ graph( 300, 200, -1.5, 1.5, -2, 2, (10x^9/2) / (9x^4/6)) }}}
& bob's your uncle!
