What is 3300000 in scientific notation?

Answer 1

Just slide the decimal point over until you have moved it some multiple of three times (3, 6, 9, 12) but without causing 0s to be the only thing left of the decimal point.

3300000 would be best expressed moving the decimal point to the left 6 places.

This would give us 3.3 but we need to incorporate the notation that we have moved the decimal place.

Because we moved it to the left, we must show that the actual number is bigger than 3.3 so the exponent is positive. We moved it exactly 6 places so the final answer is 3.3x106
