Answer 1

Ответ:

Пошаговое объяснение:

√343×3×√168 = 7√7×3×2√42=294√6

Answer 2

Let's simplify the expression step by step:

1. √343 = √(7^2) = 7
2. √168 = √(2^2 * 3 * 7) = 2√(3 * 7)

Now, let's put both parts of the expression back together:

√343 * 3 * √168 = 7 * 3 * 2√(3 * 7)

Next, multiply the numerical values:

7 * 3 = 21

The simplified expression becomes:

21√(3 * 7)

Now, √(3 * 7) = √21

Therefore, the final simplified expression is:

21√21

None of the provided options match the simplified expression 21√21.
