Answer 2

We can simplify the expression using basic algebra and simplification of radicals:

First, we can simplify the radicals within the parentheses:

√20 = √(4*5) = 2√5

Similarly,

√8 = √(4*2) = 2√2

Substituting these values in the expression, we get:

(10 + √5) * 2√5 - 5 * 2√2

Simplifying further, we can distribute the 2√5 to each term in the first part of the expression:

20√5 + 2√25 - 10√2

We can simplify √25 to 5 and then combine like terms:

20√5 + 10 - 10√2

The final simplified form of the expression is:

10 + 20√5 - 10√2

So (10+√5)√20-5√8 is equal to 10 + 20√5 - 10√2.
