The scientific notation is a way to write a very large or a very small number in the product of a decimal form of number [generally between 1 and 10]and powers of ten.

In the given there are 8 digits, then the given number in scientific notation can be written as

\(91,910,000=9.191\times10,000,000=9.191\times10^7\)
