Algebra.Com's Answer #31635 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! Evaluate the factorial expression \n" ); document.write( "100!/98! 2! \n" ); document.write( "100!=[100*99*{98*97*96*.........*3*2*1}] \n" ); document.write( "98!=98*97*96*.........*3*2*1 \n" ); document.write( "HENCE 100!/98!=100*99....AS 98,97,96,......3,2,1 CANCEL EACH OTHER \n" ); document.write( "IN FACT WE CAN WRITE 100!=100*99*98! \n" ); document.write( "SO WE GET 100!/98!2! = 100*99/2*1=50*99=4950 \n" ); document.write( " |
