1.	Define significant figures. State the rules for determining significant figures.
Answer» tion:The term significant figures refers to the number of important SINGLE DIGITS (0 through 9 inclusive) in the coefficient of an expression in scientific notation . The number of significant figures in an expression INDICATES the CONFIDENCE or precision with which an engineer or scientist states a quantity.1.Non-zero digits are always significant.2.Any zeros between two significant digits are significant.3.A final zero or TRAILING zeros in the decimal portion ONLY are significant.
