Q. How do you write 66,000 in scientific notation?______×10______
Move Decimal 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 66,000, the decimal point is currently at the end of the number (after the last zero), and we need to count how many places we move it to the left to get a number between 1 and 10.
Convert to 6.6: Moving the decimal point 4 places to the left from 66,000 gives us 6.6. This is because 66,000 is the same as 66,000.0, and moving the decimal point 4 places to the left turns it into 6.6000, which we can write as 6.6.
Multiply by 104: Now that we have the number 6.6, which is between 1 and 10, we need to multiply it by 10 raised to the power of the number of places we moved the decimal point. Since we moved the decimal 4 places, we multiply 6.6 by 104.
Combine for Scientific Notation: Putting it all together, 66,000 in scientific notation is written as 6.6×104.
