Algebra.Com's Answer #753669 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! this is the same as (x^2-1)/x \n" ); document.write( "That is 5+3+2 sqrt(15)-1 divided by sqrt (5) +sqrt (3) \n" ); document.write( "multiply (7+2 sqrt(15) by the conjugate of the denominator sqrt(5)- sqrt(3). Multiply the denominator by the conjugate.\r \n" ); document.write( "\n" ); document.write( "This will yield 7 sqrt(5)-7 sqrt(3)+10 sqrt(3)-2 sqrt (45) divided by 2 \n" ); document.write( "The numerator simplifies to 3 sqrt(3)+ sqrt(5) \n" ); document.write( "The denominator is 2 \n" ); document.write( "the answer is 0.5 (sqrt (5)+3 sqrt (3)) \n" ); document.write( " |
