Answer:
All the numbers in scientific notation written in the form a × 10b, where b is an integer and the coefficient a is a non-zero real number between 1 and 10 in absolute value.
To convert 19800 into scientific notation also known as standard form, follow these steps:
Move the decimal 4 times to left in the number so that the resulting number, m = 1.98, is greater than or equal to 1 but less than 10
Since we moved the decimal to the left the exponent n is positive
n = 4
Write in the scientific notation form, m × 10n
= 1.98 × 104
