11 answers
yes
looking at it, the number parts are about 16, so you have two significant digits, so the answer is
1.6*10^7
I do not know why your teacher presented four digits in the answers, it is obviously he/she does not understand scientific notation and significant digits.
1.6*10^7
I do not know why your teacher presented four digits in the answers, it is obviously he/she does not understand scientific notation and significant digits.
So the answer is B?
