Answer 6

Oops! I typed it wrong, I need to factor x^3+27

Answer 7

so in other words there are 2 equations to this

Answer 8

oh ok that is more like it

Answer 9

One way to do this is to take log base 3 on both sides.
You get
3logx=log27
=3logx=3
logx=1
Since its base 3
x=3^1=3

Answer 10

oh in that case, x=-3

Answer 11

What's log base?

Answer 12

I need to factor x^3+27

Answer 13

Okay,lets try it differently,
x^3-3x^2+3x^2-9x+9x+27=
(x+3)(x^2-3x+9)=0
This gives x=-3 as the only real root.
