Flashcard 4 - Math Flashcard Set for the PSAT/NMSQT Exam


The correct answer is:



Written as a scientific notation, the number becomes:

\[8.52 \;x \;10^{10}\]

It is understood that the original number had a decimal point after the last “0”. To get the correct notation, the decimal point had to be moved 10 places to the left, thus, the exponent of 10. Note: For very small numbers where the decimal has to be moved several places to the RIGHT, the exponent would be negative.
