When you multiply exponential expressions of the same base you add the exponents.
\n" ); document.write( "Like in this example,
\n" ); document.write( "\"x%5EM%2Ax%5EN=x%5E%28M%2BN%29\"
\n" ); document.write( "\"y%5E%283%2F8%29%2A%28y%5E%28-3%2F8%29+%2B+9y%5E%285%2F8%29%29\"
\n" ); document.write( " Distributive property.
\n" ); document.write( " Exponent addition rule from above.
\n" ); document.write( "\"y%5E%283%2F8%29%2A%28y%5E%28-3%2F8%29+%2B+9y%5E%285%2F8%29%29=y%5E%280%29%2B9y%5E%281%29\"Simplify.
\n" ); document.write( "\"y%5E%283%2F8%29%2A%28y%5E%28-3%2F8%29+%2B+9y%5E%285%2F8%29%29=1%2B9y\"Final answer, remember \"y%5E0=1\".
\n" ); document.write( "Your answer is 2.
