Answer:
In scientific notation, a number is typically expressed as a coefficient multiplied by a power of 10. To convert the number 20,612,439 into scientific notation, you need to move the decimal point to create a coefficient between 1 and 10 and determine the exponent of 10.
Start by moving the decimal point in 20,612,439 to the left so that you have a number between 1 and 10. In this case, you can move it six places to the left:
20.612439
Now, your coefficient is 2.0612439, and you've moved the decimal point six places to the left. To represent this in scientific notation:
2.0612439 x 10^6
So, 20,612,439 in scientific notation is approximately 2.0612439 x 10^6.
