Kneel and beg for a GRE prep plan!! GRE Math Help!

1. Accumulate more words - increase your vocabulary.

2. Talk to classmates, teachers and others in English in the classroom, on campus, etc. – improve your speaking skills.

3. Memorize more English essays and texts - accumulate sentence patterns.

4. Read books about English often, speak English often, and have English conversations with others – organize language.

5. Improve English grammar and master relevant knowledge - master sentence structure and grammar.

Total Solution:

Step 1: Recite a lot of original sentences, dialogues, and life idioms.

Step 2: Digest the materials that you have memorized every day, and use your imagination to perform them in an immersive way.

Step 3: Keep a journal. This habit seems to be practicing writing, but it is actually a wonderful way to practice speaking. While you're writing, your brain is doing intense English gymnastics. Thinking in English is an advanced method of oral training.

Step 4: Read a lot of newspapers, magazines, stories, and essays, and then retell them. (Super hint: it's "retelling" instead of "memorizing.") The retelling of the same article should be rolled over and over again.

Step 5: Gradually transition to daily thinking activities in English for a year or so. Whenever you encounter a word or sentence that you don't know, record it in the notebook, solve it intensively, and update and review it regularly.

There is a 17-day memorization method on the Internet, and there is a 10-day memorization method library.

a prime b integer c a multiple of d prime e square of odd number.

The divisor of a prime number is itself and itself by prime number analysis such as 2, 3, 5, 7.

If it is 1 exclusion option e b

If it is 3 exclude c

So choose d and have a good life.

The answer to the D question means: a positive integer with two different divisors greater than 1 and only two.

First of all, every positive integer n greater than 1 has at least 2 divisors, one is 1, and the other is itself n, so the title says that there is only 1 divisor in addition to 1 and n, set to p, if n is not perfectly squared, then n p is also a factor of n, and is not equal to p, which is contradictory.

If p is not prime, then p has a divisor other than 1 and p, which is also a divisor of n, which is also a contradiction.

So n=p, and p is prime.

Here's an example:

For example, 4 and 9 are both positive integers that satisfy the topic.

Because 4 has two divosors that are greater than 1: 2 and 4; 9 has two divosors that are greater than 1: 3 and 9).

Then a is definitely not true, and neither 4 nor 9 is a prime number.

b is also not true, because 9 is not an even number.

c is also not true, because 4 is not a multiple of 3.

e is also not true because 4 is 2 squared, and 2 is not an odd number.

Therefore d is correct.
