What number is 10^4?

OpenStudy (compassionate):

Hi, 7.09 x 10^4 Which is the same thing as 7.09 x 100,000 = 70, 900

OpenStudy (compassionate):

Oops. Didn't mean to snipe you, Maths. Didn't say you were typing.

OpenStudy (mathstudent55):

No problem. We are all trying to help, but be careful there. 10^4 = 10,000, not 100,000.

OpenStudy (mackenzie2013):
