What is 49.9 crore in scientific notation? Here we will show you how to convert 49.9 crore into scientific notation. We start by writing 49.9 crore (forty-nine crore ninety lakh) in decimal notation (decimal form), like this:
49,90,00,000
Scientific notation is a way to express large numbers, like the decimal number above, in a smaller format. You can see this format represented below. Note that 'm' is a number less than 10, and 'n' is an integer.
m × 10n
All whole numbers have an implied decimal point after the last digit. Therefore, 49,90,00,000 can also be written as '49,90,00,000.'.
To find 'm' in the equation above, we write down 49.9 crore using only the numbers. In other words, we take out the commas from its decimal form and place a decimal point at the end of the string of numbers. Then we move the decimal point to the left until the number is less than 10, and then remove any trailing zeros. This leaves us with 4.99, the resulting value of m:
499000000.
4.99000000
4.99
To find 'n' in the equation above, we simply count how many times we moved the decimal point to the left. We moved it 8 times, so n is 8.
That's all there is to it! Now we have 49.9 crore in scientific notation, as follows:
49.9 crore = 4.99 × 108
