You can put this solution on YOUR website!
Let's review the rules of exponents. In these rules, the \"variables\" stand for any expression (unless there is a note to the contrary). They are numbered so they can be referred to by number, not because any of them are more important or useful than another.)
  1. A power of a power: \"%28a%5En%29%5Em+=+a%5E%28n%2Am%29\"
  2. Multiplication with the same base: \"a%5En+%2A+a%5Em+=+a%5E%28n+%2B+m%29\" (Pay close attention to the difference between this rule and rule #1!)
  3. Division with the same base: \"%28a%5En%29%2F%28a%5Em%29+=+a%5E%28n+-+m%29\"
  4. Negative exponents: \"a%5E%28-n%29+=+1%2F%28a%5En%29\" or \"1%2F%28a%5E%28-n%29%29+=+a%5En\". In words, \"a%5E%28-n%29\" stands for the reciprocal of a^n.
  5. Zero exponents: \"a%5E0+=+1\" Note: a must not be zero!
  6. Fractional exponents (where \"n\" and \"m\" are positive integers):
    • \"a%5E%281%2Fn%29+=++root%28n%2C+a%29\". So \"a%5E%281%2F2%29+=+sqrt%28a%29\" , \"a%5E%281%2F3%29+=+root%283%2C+a%29\" , \"a%5E%281%2F4%29+=+root%284%2C+a%29\" , etc.}}}
    • Using the above rule and rule #1 together: \"a%5E%28n%2Fm%29+=+%28+root%28m%2C+a%29%29%5En+=+root%28m%2C+a%5En%29\"
  7. The pseudo-distributive property. This property is not the distributive property but it does look a little like the distributive property: \"%28a%2Ab%29%5En+=+a%5En%2Ab%5En\"
  8. Exponents apply only to what is immediately in front of them! If the symbol immediately in front of an exponent is a grouping symbol, then the exponent is applied to the entire expression in the grouping symbol. Examples:
    • \"4%5E2+=+4%2A4\"
    • \"-4%5E2+=+-%284%2A4%29+=+-16\"
    • \"%28-4%29%5E2+=+%28-4%29%2A%28-4%29+=+16\". Note the difference between this example and the previous one. Here a \")\" is right in front of the exponent. So the exponent applies to everything in the parentheses. In the previous example, a \"4\" is right in front of the exponent. So the exponent applies only to the 4 (and not the \"-\"!)
    • \"x+%2B+3%5E2+=+x+%2B+3%2A3+=+x+%2B+9\"
    • \"%28x+%2B+3%29%5E2+=+%28x+%2B+3%29%2A%28x+%2B+3%29+=+x%5E2+%2B6x+%2B9\"

\n" ); document.write( "Now let's try to solve your problems.
\n" ); document.write( "1) Use the rules of exponents to evaluate or simplify. Write without negative exponents.
\n" ); document.write( "3*4^0 = ____
\n" ); document.write( "According to PEMDAS (the order of operations) we need to simplify the exponent before doing the multiplication. So we need to figure out 4^0 first. Using rule #5 we find that 4^0 = 1. Substituting this in we get
\n" ); document.write( "3*1 = ____
\n" ); document.write( "which, of course, is 3.
\r
\n" ); document.write( "\n" ); document.write( "2) Use the rules of exponents to evaluate or simplify. Write without negative exponents.
\n" ); document.write( "1 / 4^-2 = ____
\n" ); document.write( "Using the 2nd variation of rule #4:
\n" ); document.write( "\"1%2F%284%5E%28-2%29%29+=+4%5E2+=+16\"
\r
\n" ); document.write( "\n" ); document.write( "3) Use the rules of exponents to evaluate or simplify. Write without negative exponents.
\n" ); document.write( "(1/4)^-1/2 = _____
\n" ); document.write( "Using rule #1, in \"reverse\", we can rewrite this as:
\n" ); document.write( "\"%28%281%2F4%29%5E%28-1%29%29%5E%281%2F2%29\"
\n" ); document.write( "Then, using rule #4, the expression in the parentheses can be simplified: \"%281%2F4%29%5E%28-1%29+=+4%5E1+=+4\". Substituting we get:
\n" ); document.write( "\"%284%29%5E%281%2F2%29\" which, according to rule #6, is \"sqrt%284%29+=+2\"
\r
\n" ); document.write( "\n" ); document.write( "4) Use the rules of exponents to evaluate or simplify. Write without negative exponents.
\n" ); document.write( "(bm)^-3 = ____
\n" ); document.write( "Using rule #1 again we can rewrite this as:
\n" ); document.write( "\"%28%28bm%29%5E3%29%5E%28-1%29\"
\n" ); document.write( "Using rule 7:
\n" ); document.write( "\"%28b%5E3%2Am%5E3%29%5E%28-1%29\"
\n" ); document.write( "Using rule #4:
\n" ); document.write( "\"1%2F%28b%5E3%2Am%5E3%29\"
\r
\n" ); document.write( "\n" ); document.write( "5) Use the rules of exponents to evaluate or simplify. Write without negative exponents.

\n" ); document.write( "Using rule #4 we get
\n" ); document.write( "\"y%5E%28-3%29+=+1%2Fy%5E3\"
\r
\n" ); document.write( "\n" ); document.write( "6) Use the rules of exponents to evaluate or simplify. Write without negative exponents.
\n" ); document.write( "(-243)^3/5 = ____
\n" ); document.write( "Using the second variation of rule #6:
\n" ); document.write( "\"%28-243%29%5E%283%2F5%29+=+%28root%285%2C+-243%29%29%5E3\"
\n" ); document.write( "Since \"%28-3%29%5E5+=+-243\" \"root%285%2C+-243%29+=+-3\". Substituting into the above we get
\n" ); document.write( "\"%28-3%29%5E3+=+-27\"
\r
\n" ); document.write( "\n" ); document.write( "7) Use the rules of exponents to evaluate or simplify. Write without negative exponents.
