how many times greater is 6.3 x 10^-5 than 3.5 x 10^-6 express your answer using either standard notation or scientific notation
To find how many times greater 6.3 x 10^-5 is than 3.5 x 10^-6, we can divide the two numbers:
(6.3 x 10^-5) / (3.5 x 10^-6) = (6.3 / 3.5) x 10^-5 / 10^-6 = 1.8 x 10^1 = 18
So, 6.3 x 10^-5 is 18 times greater than 3.5 x 10^-6.
