document.write( "Question 7150: 1st of all, sorry about the previous question, i was looking in the wrong section, i found something similar in the square root section and understand better now. ok, I have to simplify 243 to the power of - 2/5, i can get as far as 1 divided by 5th root of 243 to the power of 2, but after that my mind goes blank. the answer given is 1/9 and i need help working out how they got that. thank you in advance \n" ); document.write( "

You can put this solution on YOUR website!
Well, your first step is ok:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28243%29%5E%28-2%2F5%29\" = \"1%2F%28243%29%5E%282%2F5%29\"\r
\n" ); document.write( "\n" ); document.write( "Finding the square of a number is relatively easy.
\n" ); document.write( "Finding the fifth root of a number isn't. But you can do both with your calculator.\r
\n" ); document.write( "\n" ); document.write( "Type in 243 then ^ then (2/5) then hit the enter or = key.\r
\n" ); document.write( "\n" ); document.write( "You should get: \"%28243%29%5E%282%2F5%29+=+9\"\r
\n" ); document.write( "\n" ); document.write( "So the answer of 1/9 is correct.
\n" ); document.write( "
\n" );
