Respected sir,
During the calculation of significant figures in scientific notation we ignore the power i.e 10^n, but for the the first part,do we write all the numbers or do we again check significant figures(after evaluating) in that value?
Ex: 4.0100 * 10^-3?-Find no of significant figures.
SIGNIFICANT FIGURE is 3 or 5
(5,if and can we write as 4.01 *10^-1)?
