What is 187189915062 in scientific notation?

Answer 1

1.87189915062 x 1011 or you can use 1.87 x 1011 if you'd like to round off some. Here are some steps to the answer. 187189915062 => 187,189,915,062 => 1.87189915062 x 1011 => 1.87 x 1011 for a rounded off answer. Note that we put in a decimal with only one significant digit to the left of that decimal. In this case, it's the 1, as 1.87 is our number. That leaves everything else to the right of the decimal. Then we multiply that by an appropriate power of ten to make it equal to the original number. In this case we need 1011 to do the job. We moved the decimal in the original number 11 places from its original position all they way to the left to leave just that one significant digit to the left of the new location of that decimal point.
