Q. How do you write 380 in scientific notation?_____×10_____
Move Decimal Point Left: To write a number in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10. We do this by moving the decimal point in the number to the left until only one non-zero digit remains to the left of the decimal point. The number of places we move the decimal point will be the exponent of 10. For the number 380, the decimal point is currently at the end of the number (implied as 380.0). We need to move it two places to the left to get 3.80.
Express in Scientific Notation: Now that we have the number 3.80, which is between 1 and 10, we can write it in scientific notation. The decimal point was moved two places to the left, so the exponent of 10 will be 2. The scientific notation for 380 is 3.80×102.
