1)3 then square root sign 45 + 7 then square root sign 20
\n" ); document.write( "3*sqrt(45)+7sqrt(20)
\n" ); document.write( "=3*3*sqrt(5) + 7*2*sqrt5
\n" ); document.write( "=9sqrt(5) + 14sqrt(5)
\n" ); document.write( "=23sqrt(5)
\n" ); document.write( "-----------------------
\n" ); document.write( "2)3 then cubed in the square sign then 16 under the square sign + cubed then 54 under the square root sign.
\n" ); document.write( "3*(16)^(1/3) + (54)^(1/3)
\n" ); document.write( "-----------------------
\n" ); document.write( "= 3*2*2^(1/3) + 3*2^(1/3)\r
\n" ); document.write( "\n" ); document.write( "= 6*2^(1/3) + 3*2^(1/3)\r
\n" ); document.write( "\n" ); document.write( "= 9*2^(1/3)
\n" ); document.write( "Or
\n" ); document.write( "=9*cuberoot of 2
\n" ); document.write( "--------------------
