Q. How do you write 28,000 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 to the left until we have a number between 1 and 10. For 28,000, the decimal point is initially after the last zero, and we need to move it to between the 2 and the 8.
Count decimal point places: Count the number of places the decimal point moves from its original position to its new position between the 2 and the 8. This will give us the exponent for the power of 10.
Determine exponent: The decimal point moves 4 places to the left (28,000.0 becomes 2.8). Therefore, the exponent for the power of 10 is 4.
Write in scientific notation: Now we can write 28,000 in scientific notation as 2.8 multiplied by 10 to the power of 4.
