Question about regression formula

[#1]

Hi,

I ran the polynomial regression in QlikView, and got the formula result like this:

Y = 2.84442e-005x^4 + 0.0078937x^3 + 0.40151x^2 - 5.1188x + 11.309

What does "2.84442e-005x^4" mean? Is it e-005 * x^4 or e-(005 * x^4)? And what is 005? is it .005?

Thank you!
