sqrt%282%29%2A%289%2Asqrt%283%29-5%2Asqrt%284%29%29 Start with the given expression.


sqrt%282%29%2A%289%2Asqrt%283%29-5%2A2%29 Take the square root of 4 to get 2.


sqrt%282%29%2A%289%2Asqrt%283%29-10%29 Multiply 5 and 2 to get 10


sqrt%282%29%2A9%2Asqrt%283%29-sqrt%282%29%2A10 Distribute.


9%2Asqrt%282%2A3%29-10%2Asqrt%282%29 Combine the roots.


9%2Asqrt%286%29-10%2Asqrt%282%29 Multiply 2 and 3 to get 6.


So sqrt%282%29%2A%289%2Asqrt%283%29-5%2Asqrt%284%29%29=9%2Asqrt%286%29-10%2Asqrt%282%29
