A certain human red blood cell has a diameter of 0.000007 meters.Write an expression that represents this diameter, in meters in scientific notation. Equation
Accepted Solution
A:
By definition we have to: Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large or too small to be written in a conventional manner. The use of this notation is based on powers of base 10. A number written in scientific notation follows the following pattern: [tex]m * 10 ^ e
[/tex] The number m is called "mantissa" and e the "order of magnitude" For this case we have: 0.000007 Using the definition, we have that the measure of the diameter in scientific notation is: [tex]0.000007 = 7 * 10 ^ {-6}
[/tex] Answer: An expression that represents this diameter, in meters in scientific notation is: [tex] 7 * 10 ^ {-6}[/tex]
