Question

(1/7+корень47)+(1/7-корень47)

Answer 1

(1/7+√47)+(1/7-√47)=1/7+1/7+√47-√47=2/7.

Ответ: 2/7.

Answer 2

To simplify the expression, let's first evaluate the individual parts:

1. Calculate the square root of 47: √47 ≈ 6.8556546 (rounded to 7 decimal places).
2. Now, let's add the two fractions:

(1/7 + √47) + (1/7 - √47)

Since the denominators are the same (both fractions have 7 as the denominator), we can combine the numerators:

(1 + √47) + (1 - √47)

Next, let's combine like terms:

1 + √47 + 1 - √47

The √47 and -√47 cancel each other out, leaving us with:

1 + 1

Finally, add the two numbers together:

1 + 1 = 2

So, the simplified result of the expression is 2.
