\"%28-2y%5E3%29%5E%283%2F5%29\" = \"%28%28-2%29%2Ay%5E3%29%5E%283%2F5%29\" = \"%28-2%29%5E%283%2F5%29+%2A+y%5E%283%2A3%2F5%29\" = \"%28-2%29%5E%283%2F5%29%2Ay%5E%289%2F5%29\" = \"-1.515716567+%2A+y%5E%289%2F5%29\"
\n" ); document.write( ".................
\n" ); document.write( "i believe this is the answer.
\n" ); document.write( "for some reason my calculator was giving me fits when i tried to solve (-2)^(3/5) directly.
\n" ); document.write( "it did, however, allow me to do (-2)^3 first and then do -8^(1/5) which i was able to confirm works with other numbers.
\n" ); document.write( "i checked with calculators on the web and discovered this is a common problem with calculators and fractional exponents.
\n" ); document.write( "fortunately (x)^(3/5) is the same as (x^3)^(1/5) and that works.
\n" ); document.write( "i'm reasonably certain this is the correct answer but you can wait for other tutors to confirm if you wish.\r
