Answer:

3.12 * [tex]10^-^7[/tex]

Step-by-step explanation:

Scientific notation requires a decimal with only a ones digit and decimal digits with a power of 10.

0.000000312 can be written as 3.12 times a power of 10.

Since you would have to move the decimal point of '3.12' 7 times to the left in order to get '0.000000312', the power of ten should be -7.

Your answer should be 3.12 * [tex]10^-^7[/tex].
