Answer 2

To simplify the expression √891b - √0.8√539b + 2√275b, you can use the properties of square roots. First, let's simplify each term separately:

1. √891b = √(9 * 99 * b) = 3√(99b)

2. √0.8√539b = √(0.8 * 539 * b) = √(431.2b) ≈ √(432b) (rounded to a nice number)

3. 2√275b = 2√(25 * 11 * b) = 10√(11b)

Now, let's rewrite the expression with these simplified terms:

3√(99b) - √(432b) + 10√(11b)

Now, you can't combine these square roots further because the expressions inside the square roots have different factors. So, the simplified expression is:

3√(99b) - √(432b) + 10√(11b)
