Answer:
2.12x10 to the -3rd power
Step-by-step explanation:
To put this into scientific notation, you first have to get a number that is not 0 in the one's place by moving the decimal:
0.00212
0002.12
It moved three places to the right, so the exponent will be negative:
2.12x10 to the -3 power
That is your answer
Hope this helps!
