Answer: B. 0.000000004109
Explanation:
Concept:
The term "E" is usually used in calculators or on-screen which stands for exponents. It has been used to display numbers in scientific notations.
Scientific notation is a form of presenting very large numbers or very small numbers in a simpler form. Usually in the form of [ a × 10ᵇ ] where a is a number 0<a<10 and b are integer exponents.
"E" in simpler words is basically the base "10" in scientific notation, while the number after "E" would be the exponents on "10"
Solve:
Given = 4.109 E -9
E -9 = 10⁻⁹ = 0.000000001
10⁻⁹ moves the decimal point 9 places to the left, or means there are 9 places to the right of the decimal point.
4.109 × 0.000000001 = 0.000000004109
Hope this helps!! :)
