\n" );
document.write( "The geometric mean of two positive number x and y is the number squared xy. If x and y are positive rational numbers, can you conclude that their geometric mean is also rational? Explain \n" );

WILL ALSO BE RATIONAL AS SUM OF 2 RATIONAL NUMBERS IS RATIONAL AND THEIR DIVISION BY 2 WILL NOT CHANGE THEIR NATURE. \n" ); document.write( "The geometric mean of two positive number x and y is the number squared xy. \n" ); document.write( "NO..IT IS SQUARE ROOT OF THEIR PRODUCT (XY) = (X*Y)^0.5 \n" ); document.write( " If x and y are positive rational numbers, can you conclude that their geometric mean is also rational? Explain \n" ); document.write( "NO.SINCE THIS INVOLVES SQUARE ROOT,IT COULD BE IRRATIONAL .SUPPOSE X=2 AND Y=1...THEIR G.M. IS SQRT.(2*1)=SQRT.(2)WHICH IS IRRATIONAL \n" ); document.write( " |
