Answer 2

Answer:

Step-by-step explanation:

√80 = √16 × √5 = 4√5

√27 = √9 × √3 = 3√3

√45 = √9 ×√5 = 3√5

Now the expression is 4√5 + 3√3 - 3√5

You can rearrange the expression because of PEMDAS and get 4√5 - 3√5 + 3√3

4√5 - 3√5 is just √5

Now you have √5 + 3√3

Since there are no more like terms between √5 and 3√3, you can't simplify the expression anymore and that is your final answer.
