Answer 3

2 radical 5 + 3 radical 25
You can't calculate the square root of 5 without a calculator (Unless you're taking up calculus)
So we leave 2 radical 5 as is

3 radical 25

A number under a radical sign (in this case 25) means you take the square root of that number
Square root = the number you multiply by itself to get another number
Now what do you multiply by itself to get 25?

5

We can simplify sqrt 25 as simply 5 and multiply it to the number outside the radical
3 sqrt 25
3*5
=15

Then you combine the two

15+2 radical 5
