what does 9E-4 mean? It came up as an answer to a problem i went through on my calculator
it is the same as 9x10^-4, or .0009
In scientific notation, a number is written in the form of A x 10^B, where A is a number between 1 and 10 (excluding 10) and B is an integer.
In this case, 9E-4 can be expressed as 9 x 10^(-4).
The "E" in 9E-4 represents the scientific notation exponent, which means "times ten raised to the power of." In this case, it indicates that the number should be multiplied by 10 raised to the power of -4.
So, 9E-4 means 9 times 10 to the power of -4, which is equivalent to 0.0009 or 9 thousandths (0.0009 = 9/10000).
