\n" ); document.write( "\n" ); document.write( "The major goal of this problem is to teach you using your calculator for similar tasks.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First, you make straightforward calculations to find the logarithm values, using given formula.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Next, you potentiate to restore the numbers from the found logarithm values.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In this problem, there is NO ANY NEED to manipulate with formulas for logarithms.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This problem is not intended for such manipulations.\r
