Algebra.Com's Answer #31641 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! Show that each equattion is true by simplifying the following: \n" ); document.write( "USE A^-B^2=(A+B)(A-B)...RATIONALISE THE IRRATIONAL N.R....OR...D.R BY MULTIPLYING WITH CONJUGATE FACTOR. \n" ); document.write( "a.) 1/(sqrt(x)+sqrt(y)) = (sqrt(x)-sqrt(y))/(x-y) \n" ); document.write( "MULTIPLY N.R AND D.R WITH {SQRT(X)-SQRT(Y)} \n" ); document.write( "{SQRT(X)-SQRT(Y)}/[{SQRT(X)}^2-{SQRT(Y)}^2]=(sqrt(x)-sqrt(y))/(x-y)\r \n" ); document.write( "\n" ); document.write( "b.) (sqrt(x+h)- sqrt(x))/h = 1/(sqrt(x+h)+sqrt(x)) \n" ); document.write( "SAME WAY AS ABOVE ..MULTIPLY N.R AND D.R WITH (sqrt(x+h)+ sqrt(x)) \n" ); document.write( " |
