c) √7
d) -11√7

you

Simplify

Observe that all roots are similar, because they are square roots.

To simplify this products, we can write only one root and multiply all sub-radical numbers, as follows

It's better to maintain the product as factors, so, let's express each number in a power

Then, all square powers can go out the root

Therefore, the answer here is

Simplify

Observe that all roots are exactly the same, we proceed to sum and subtract the whole part of each term

Therefore, the answer is

Which expression is equal to

Let's express each root in factors

Then, we solve the root for 4 and 9

Then, we subtract

Therefore, the right answer is D.

only 10/60 isn't equivalent

hope this : )
