Note: to do a radical sign (like sqrt%283%29), simply type: sqrt(3) surrounded by 3 curly brackets (this symbol: { and }) on both sides. Check the source if you want to see it.
2sqrt%283%29+%2A+5sqrt%2827%29

2sqrt%283%29+%2A+5sqrt%283%2A9%29 Rewrite 27 as 3*9

2sqrt%283%29+%2A+5sqrt%283%29%2Asqrt%289%29%29 Break up the square root. (ie use this property: sqrt%28xy%29=sqrt%28x%29sqrt%28y%29)

%282%2A5%29%28sqrt%283%29+%2A+sqrt%283%29%29%2Asqrt%289%29%29 Group the whole numbers and the sqrt%283%29 terms together.

10%283%29%2Asqrt%289%29%29 Multiply

30%2Asqrt%289%29%29 Take the square root of 9

30%2A3=90 So this is your answer
