For square roots you can use the Math.Sqrt method and for higher roots the Math.Pow method: double d1 = Math.Sqrt(45); double d2 = -d1; double d3 = Math.Pow(42 1.0/6.0); double d4 = -d3; double d5 = Math.Pow(76 1.0/20.0); double d6 = -d5; double d7 = Math.Pow(380 1.0/1000.0); double d8 = -d7; double d9 = Math.Pow(548 1.0/60.00); double d10 = -d9;
