sqrt%28x%2F5%29+%2B+sqrt%2820x%29+-+sqrt%2845x%2F4%29
sqrt%28x%29%2A%28sqrt%281%2F5%29+%2B+sqrt%2820%29+-+sqrt%2845%2F4%29%29
sqrt%28x%29%2A%28sqrt%281%2F5%29+%2B+2%2Asqrt%285%29+-+%283%2F2%29%2Asqrt%285%29%29
sqrt%28x%29%2A%28sqrt%281%2F5%29+%2B+%281%2F2%29%2Asqrt%285%29%29
sqrt%28x%29%2A%28%282+%2B+5%29+%2F+%282%2Asqrt%285%29%29%29
sqrt%28x%29%2A%287+%2F+%282%2Asqrt%285%29%29%29
