Need help in math pre algebra

1c

2d

3e

4a

Step-by-step explanation:

Simplifying all terms in 1, we get 1, 2, -2, 1/16. So the correct order is -2, 1/16, 1, 2. So the answer is C

Simplifying all terms in 2, we get 6, sqrt30, 1, and 4. While we can't completely simplify sqrt30 easily, we know that 5 squared equals 25 and 6 squared equals 36. 30 is in between, so we can assume sqrt30 is in between 5 and 6. So the answer is d.

Simplifying all terms in 3, we get 1/125, sqrt3, 1, and 0. Again, we can assume sqrt3 is between 1 and 2. So the answer is e.

Simplifying all terms in 4, we get 32, sqrt101, 25, sqrt399. We can assume sqrt101 is close to sqrt100, which is 10. We can also assume that sqrt399 is close to sqrt400, which is 20. So the answer is a.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
