Answer 2

To calculate the expression 21 - (1 - (√7/7)), you can follow these steps:

1. Calculate √7, which is the square root of 7. √7 ≈ 2.6458 (rounded to four decimal places)

2. Calculate (√7/7): (√7/7) ≈ (2.6458/7) ≈ 0.3780 (rounded to four decimal places)

3. Calculate (1 - (√7/7)): (1 - 0.3780) ≈ 0.6220 (rounded to four decimal places)

4. Finally, subtract the result from 1: 1 - 0.6220 = 0.3780

So, 21 - (1 - (√7/7)) is approximately equal to 20.3780 when rounded to four decimal places.
