To find : Write 12,400,000 in scientific notation.
Solution : We have given 12,400,000 .
Steps to write in scientific notation :
Step 1 : If a number has n digit we move decimal point ( n-1) place to left and to balance , multiply by \(10^{n-1}\).
We can see there are n = 8 in 12,400,000 .
So, we move decimal point 7 place to the left .
