Verified step by step guidance1
Identify the decimal number given: 0.00097.
To write a number in scientific notation, express it as a product of a number between 1 and 10 and a power of 10. So, move the decimal point in 0.00097 to the right until you have a number between 1 and 10.
Count how many places you moved the decimal point. For 0.00097, moving the decimal point 4 places to the right gives 9.7.
Since you moved the decimal point 4 places to the right, the exponent on 10 will be negative 4, because the original number is less than 1.
Write the number in scientific notation as \(9.7 \times 10^{-4}\).
