How do you solve ^16 sqrt -7^16?
\n" ); document.write( "-------------
\n" ); document.write( "It's not an equation, and there's no variable, so there's nothing to solve.
\n" ); document.write( "----
\n" ); document.write( "What does ^16 mean?
\n" ); document.write( "If it's the 16th root:
\n" ); document.write( " $\"root%2816%2C%28-7%29%5E16%29%29\"$
\n" ); document.write( "= 7 or -7
\n" ); document.write( "---------
\n" ); document.write( "If you expand (-7)^16, you get a big positive integer.
\n" ); document.write( "Then there are 16 16th roots of it, ą 7 being the most obvious.
\n" ); document.write( "-------
\n" ); document.write( "If you take $\"root%2816%2C%28-7%29%5E16%29%29\"$ = $\"%28-7%29%5E%2816%2F16%29\"$ then it's -7.
