When doing a computer calculation, Cooper got an answer that said 1.45E−12 . What is this number in scientific notation?(1 point) Responses 1.45 ×10−12 1.45 ×10−12 1.45 +10−12 1.45 +10−12 1.45 ×1012 1.45 ×1012 −12 ×101.45
1.45 × 10^-12
To express a number in scientific notation, you need to write it in the form: a × 10^b, where a is a number between 1 and 10, and b is an exponent.
In this case, the number Cooper got is 1.45E−12. The "E" notation is a shorthand way of representing the exponent in scientific notation.
To convert this into standard scientific notation:
1. Write the numerical part, which is 1.45.
2. Replace "E" with "×10^".
3. Take the exponent value, which is −12, and write it as the exponent after "×10^".
Therefore, the number 1.45E−12 in scientific notation is 1.45 × 10^−12.
