Answer for screen readers
The scientific notation of 93,000,000 is $9.3 \times 10^7$.
Steps to Solve
-
Identify the significant figures Look at the number 93,000,000. We need to focus on the significant digits, which are 9 and 3.
-
Place the decimal point To convert to scientific notation, move the decimal point so that there's only one non-zero digit to the left. For 93,000,000, we move the decimal point after the 9, giving us $9.3$.
-
Determine the exponent Count how many places you moved the decimal. We moved it 7 places to the left, so the exponent is $7$.
-
Construct the final expression Combine the number and the exponent of ten. This gives us the scientific notation format: $$ 9.3 \times 10^7 $$
The scientific notation of 93,000,000 is $9.3 \times 10^7$.
More Information
