Using index laws to simplify this equation

**Jaydenaus** · March 9th 2013, 10:52 PM

Could anyone help me simplify this equation using index laws:

$formdata=\frac{3^{n+4}-6(3^{n+1})}{7(3^{n+2})}$

Hey Jaydenaus.

Try using the fact that 6 = 3*2 and that 3^(n+4) = 9*3^(n+2)

I would simply divide each term by $3^{n+1}$ .

I guess the question is, do you know what the "index laws" are?
