You can put this solution on YOUR website!
note that 18=9*2, 50 = 25*2, 72 = 36*2. 9, 25 and 36 are squares of 3, 5 and 6 can be taken out of squar root as 3, 5, and 6 respectively. So, you get \r
\n" ); document.write( "\n" ); document.write( "= 3.√18 - √50 + 3√72 = 3.3√2 - 5√2 + 6.2√2 = √2( 9 - 5 + 12)\r
\n" ); document.write( "\n" ); document.write( "= 16√2
