Algebra.Com's Answer #97633 by vleith(2983)![]() ![]() ![]() You can put this solution on YOUR website! There have been a bunch of problems like this one recently. You might want to check the 'recently solved' before posting a problem that is already solved several times.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "In tis problem, you can elininate the Log2 from both sides. You can just 'know that since a Log2 on the left is equal to the Log2 on the right, then the values are the same. Thus \n" ); document.write( "\n" ); document.write( "If you want to go a different way, take both sides of the equation and use the values there as exponents on the power of 2. So 2^(log2 1056) = 2^(2^a+5 + 2^a). \n" ); document.write( "That becomes 1056 Log2 2 = (2^(a+5) + 2^a) Log2 2. Since Log2 2 = 1, you get to the same equation as above.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "a = 5\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
