Yes, true.
1. All non-zero digits are always significant. 2. Zeroes between other significant figures are significant. 3. Trailing zeroes without a decimal point are not significant. 4. Trailing zeroes after a decimal point are significant. 5. Leading zeroes that come before a non-zero number are not significant. 1. 2598 has four significant figures. 2. 25005 has five significant figures. 3. 160 has two significant figures. 4. 45.800 has five significant figures. 5. 00.00589 has three significant figures.
Significant Features in a given measurement mean like specific digits from a number. The rules are: 1) Nonzero digits are always significant 2) All final zeroes after a decimal point are significant 3) Zeroes between two other significant digits are always significant 4) Zeroes used soley as placeholders are NOT significant 5) Zeroes between a decimal point and a nonzero digit are significant. 34900 would have 3 significant features. 0.0034900 would have 5. I hope that helps. I got the information from this website: http://www.hazelwood.k12.mo.us/~grichert/sciweb/phys8.htm There are tons more practice problems and info.

ExponentsExponents are used in many algebra problems, so it's important that you understand the rules for working with exponents. Let's go over each rule in detail, and see some examples. Rules of 1 There are two simple "rules of 1" to remember. First, any number raised to the power of "one" equals itself. This makes sense, because the power shows how many times the base is multiplied by itself. If it's only multiplied one time, then it's logical that it equals itself. Secondly, one raised to any power is one. This, too, is logical, because one times one times one, as many times as you multiply it, is always equal to one. Product Rule The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! Power RuleThe "power rule" tells us that to raise a power to a power, just multiply the exponents. Here you see that 52 raised to the 3rd power is equal to 56. Quotient Rule The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents. You can see why this works if you study the example shown. Zero Rule According to the "zero rule," any nonzero number raised to the power of zero equals 1. Negative Exponents The last rule in this lesson tells us that any nonzero number raised to a negative power equals its reciprocal raised to the opposite positive power.This information comes from http://www.math.com/school/subject2/lessons/S2U2L2DP.html
Rules for exponents to multiply powers, add the exponents to divide powers, subtract the exponents to find a power of a power, multiply the exponents to find a power of a quotient, apply the power top and bottom to find a power pf a product, apply the exponent to each factor in the product x0 = 1 anything to the power zero equals one x-a = 1/xa a negative exponent means "one over" the positive exponent
But according to the rules of significant figures, the least number of significant figures in any number of the problem determines the number of significant figures in the answer which, in this case, would be 11.

Use the rules of significant figures to answer the following : 22.674 * 15.05. Answer: 341.2
There are some rules for finding significant figures. here there is a problem how many significant figures in 8.00. here in 8.00 have three significant figures. Because after decimal point they may have zeros. but we have to take this as significant figures.

Four significant figures. Review you rules for significant figures. Some chemistry teachers, especially at the college level, are very concerned with significant figures.
You count the number of figures from left to right starting with the first number different from 0. Example: 205 has 3 significant figures 0.0000205 has 3 significant figures 0.000020500000 has 8 significant figures
