You can put this solution on YOUR website!
Just use a calculator. If your calculator has parentheses buttons, as many do, then you can just enter the entire expression:
\n" ); document.write( "4^(1/3)
\n" ); document.write( "32^(-3/2)
\n" ); document.write( "(18/81)^(3/4)
\n" ); document.write( "(-32)^(-2/5)

\n" ); document.write( "If your calculator does not have parentheses buttons then first convert all the fractions into decimals:
\n" ); document.write( "4^(0.3333333...) (1/3 is a repeating decimal. Use as many 3's as you like. The more you use, the closer the answer will be to the right answer.)
\n" ); document.write( "32^(-1.5)
\n" ); document.write( "(0.2222...)^(0.75) (Another repeating decimal)
\n" ); document.write( "(-32)^(-0.4)

\n" ); document.write( "If you can't figure out how to do negative exponents, then just use the positive exponent and then find the reciprocal of the answer you get. (Most calculators have a reciprocal button: $\"1%2Fx\"$ )

\n" ); document.write( "P.S. The last one can be done without a calculator if you figure out that $\"%28-2%29%5E5+=+-32\"$ and if know how fractional exponents work:
\n" ); document.write( " $\"%28-32%29%5E%28-2%2F5%29+=+%28root%285%2C+-32%29%29%5E2+=+%28-2%29%5E2+=+4\"$ \n" ); document.write( "

\n" );
