You can put this solution on YOUR website!
1. Simplify [√(32xy^7)/(√2xy)]
\n" ); document.write( "= sqrt[(32xy^7)/(2xy)]
\n" ); document.write( "= sqrt[16y^6]
\n" ); document.write( "= 4y^3
\n" ); document.write( "You are correct
\n" ); document.write( "--------------
\n" ); document.write( "2. Simplify and combine like radicals.
\n" ); document.write( "[5(forth root√(16x) + 5(forth root √625x].
\n" ); document.write( "= 5*2*4th rt of x + 5*5*4th rt of x
\n" ); document.write( "=(10+25)*4th rt of x
\n" ); document.write( "=35*4th rt of x
\n" ); document.write( "You are correct
\n" ); document.write( "-------------------
\n" ); document.write( "3. Simplify the expression by rationalizing the demoninator √[3/7].
\n" ); document.write( "= sqrt(3/7)
\n" ); document.write( "Multiply numerator and denominator by 7 to get:
\n" ); document.write( "= sqrt(21/49)
\n" ); document.write( "= [sqrt(21)]/[sqrt(49)]
\n" ); document.write( "= [sqrt(21)]/7
\n" ); document.write( "= (1/7)sqrt(21)
\n" ); document.write( "===================
