Answer 2

Ответ:

1) √32 + √50 - √98 = 4√2+ 5√2 - 7√2 = 2√2

2)√9а + √25а - √36а = 3√а + 5√а - 6√а = 2√а

Answer 3

Let's simplify these expressions step by step:

1. √32 + √50 - √98:

   First, we can factor out any perfect squares under the square roots:

   √(16 * 2) + √(25 * 2) - √(49 * 2)

   Next, simplify the square roots of perfect squares:

   4√2 + 5√2 - 7√2

   Now, combine like terms:

   (4√2 + 5√2) - 7√2 = 9√2 - 7√2 = 2√2

   So, the simplified expression is 2√2.

2. √9a + √25a - √36a:

   First, simplify the square roots of perfect squares:

   3√a + 5√a - 6√a

   Now, combine like terms:

   (3√a + 5√a) - 6√a = 8√a - 6√a = 2√a

   So, the simplified expression is 2√a.

So, the simplified expressions are:

1. 2√2
2. 2√a
