Answer 2

It seems like you're trying to simplify or perform some mathematical operations with square roots, but the notation you've used is a bit unclear. I'll do my best to interpret and simplify the expression you've provided:

(15√1,2 + √270 - 2√30) / 3

Let's break it down step by step:

1. √1,2 is the square root of 12, which is √12.

2. √270 can be simplified. √270 = √(9 * 30) = 3√30.

3. 2√30 remains the same.

Now, the expression looks like this:

(15√12 + 3√30 - 2√30) / 3

Combine like terms:

(15√12 + 3√30 - 2√30) / 3

Now, let's subtract 2√30 from 3√30:

(15√12 + √30) / 3

Now, you can't simplify it further unless you know the values of √12 and √30. You can approximate these square roots, or you can leave the expression as it is in this simplified form:

(15√12 + √30) / 3
