$\"%28-5%2F2a%5E3%29+%5E3\"$
\n" ); document.write( ".
\n" ); document.write( "There are a couple of ways that you can do this problem. Remember that the definition of
\n" ); document.write( "cubing an expression. It means multiplying by itself 3 times as in:
\n" ); document.write( ".
\n" ); document.write( "

. The numerator
\n" ); document.write( "multiplies out to $\"-5%2A-5%2A-5+=+-125\"$ and the denominator to $\"%282%2A2%2A2%2Aa%5E3%2Aa%5E3%2Aa%5E3%29=+8a%5E9\"$
\n" ); document.write( "Combining these results gives: $\"-125%2F%288a%5E9%29\"$
\n" ); document.write( ".
\n" ); document.write( "The short hand method says that when you raise a fraction to a power, both the numerator
\n" ); document.write( "and denominator get raised to that power. So:
