Hannah is not correct because the exponent should be -6

Step-by-step explanation:

Hannah is asked to convert the number 0.00000305 to scientific notation. Her answer is 3.05 × 10^6

0.00000305 to scientific notation.

To get scientific notation we move the decimal point after the first number

so we move the decimal point 6 places to the right

It becomes 3.05

we moved the decimal point 6 places to the right so we put 10^-6

3.05 * 10^-6

Hannah is not correct because the exponent should be -6

tube or goog would be a great resource to with that question
