Answer 2

Answer:

a = 4 and b = 5

Step-by-step explanation:

The simplest form of square root of eighty can be written as:

$\sqrt{80}=\sqrt{2\times2\times2\times2\times5}$

Now as it is a square root function, we will pair up the four 2's in two pairs.

And will take out $2\times2$ outside the square root.

Making the answer = $2\times2\sqrt{5}$

or $4\sqrt{5}$

So, a = 4

and b = 5
