How is (4/27)*(3)^3 = 4?

How is (4/27)*(3)^3 = 4?

When I evaluate it as a first step, I reduce the (3)^3 into 9, thus generating:

(4/27) * 9.

With a little basic multiplication, I have:
36/27, or 4/3.
Which is obviously not equal to 4!

Am I right or wrong? Where did I make an error?

@grabbitmedia,
More properly written as
(4/27) * (3³) = X

(3³) = 27

So:

(4/27) * (27) = 4

No. 3^3, or 3³, does NOT equal 9.

3^3, or 3³. = 3*3*3 = 27.

@Blickers,
The question is an ad placement for the website. An SEO whose name matches his website knows what 3 cubed is.

@nacredambition,
Thanks for the heads up. And here I was thinking I was helping some young student or adult who had gone back to school to further himself. I did see the "media" in the name, but I figured that could be the website of a teenager who's interested in video games-or maybe even created his own video game. Oh well.

Just curious, what is the purpose of a company asking a question like this-how does it help the company?
