What's -0.000009 in scientific notation?

Vocaloid (vocaloid):

hint: how many decimal places do we need to move to go from -0.000009 to 9.0?

OpenStudy (gabbyalicorn):

6?

OpenStudy (gabbyalicorn):

no 2

Vocaloid (vocaloid):

you were right the first time, 6

OpenStudy (gabbyalicorn):

Oh...

Vocaloid (vocaloid):

now, since our number is less than 1, the exponent part must be negative so that gives us -9 * 10^-6

OpenStudy (gabbyalicorn):

Oh, thank you for helping me. :)
