Write in scientific notation <br><br> (2.3x10^8)x(7.84x10^4)

Keith_Richards [23]

Answer: 1.8032 x 10^13

Step-by-step explanation: 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 ten. If your decimal is being moved to the right, then the exponent will become negative. If your decimal is being moved to the left, then the exponent will become positive.
