3%2Asqrt%2880%29%2B4%2Asqrt%28180%29 given

3%2Asqrt%2816%2A5%29%2B4%2Asqrt%2836%2A5%29 factor the numbers under the radical

3%2A4%2Asqrt%285%29%2B4%2A6%2Asqrt%285%29 pull out the squares

12%2Asqrt%285%29%2B24%2Asqrt%285%29 simplify

36%2Asqrt%285%29 add like terms and final answer

I hope this helps!
