Во втором -2 корня из 2

Answer 2

√2+3√2 = 4√2
√2-3√2=-2√2

Answer 3

Let's simplify the given expressions:

1. √2 + 3√2: To simplify this expression, we can combine like terms. Here, the like terms are both square roots of 2. Adding them together gives us: √2 + 3√2 = (1 + 3)√2 = 4√2

2. √2 - 3√2: Similarly, we can combine the like terms, which are both square roots of 2: √2 - 3√2 = (1 - 3)√2 = -2√2

So, √2 + 3√2 simplifies to 4√2, and √2 - 3√2 simplifies to -2√2.
