You can put this solution on YOUR website!
sqrt%288%29+%2B+sqrt%2818%29
this is not an equation (no equal sign), it's an expression we can simplify
Factor inside the radical to reveal perfect squares
sqrt%284%2A2%29+%2B+sqrt%289%2A2%29
Extract the square root of these squares
2%2Asqrt%282%29+%2B+3%2Asqrt%282%29
these are like terms, so we can add them
5%2Asqrt%282%29
