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( "\"log2+1056+=+log2%282%5Ea%2B5+%2B+2%5Ea%29+\"
\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 \"1056+=+2%5E%28a%2B5%29+%2B+2%5Ea\". \r
\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( "\"1056+=+2%5E%28a%2B5%29+%2B+2%5Ea\"
\n" ); document.write( "\"1056+=+2%5Ea+%2A+2%5E5+%2B+2%5Ea\"
\n" ); document.write( "\"+1056+=+32+%2A+2%5Ea+%2B+2%5Ea+\"
\n" ); document.write( "\"+1056+=+33+%2A+2%5Ea\"
\n" ); document.write( "\"+32+=+2%5E5\"
\n" ); document.write( "a = 5\r
