Convert to Scientific Notation (9.210^8)-(410^8)

$(9.2 \cdot 10^{8}) - (4 \cdot 10^{8})$

Step 1

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the $10$ . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
