56 million is 56,000,000.
A number is written is scientific notation, if it is written as :
\(x \cdot10^n\), where x is a decimal number (possibly integer), with only one digit to the left of the decimal point, and n is an integer.
thus \(56,000,000=56\cdot10^6=5.6 \cdot10 \cdot 10^6=5.6\cdot 10^7\)
Answer: \(5.6\cdot 10^7\)
