what is 3.00164502 x 10^-19 rounded to three significant figures??
plzplz

3.00*10^-19

that's what i thought, but it's an online submission and i get:
Your answer cannot be understood or graded

this is bs

try typing 3.00x10^-19

or 3.00E-19

Another possibility is 3.00*10^{-19}

Yeah, these online assignments suck until you figure out the format in which they want answers. Check the main page or something and hopefully there will be some guide on how to enter numbers with different formats.
