The brain is not very good, who is a little witty to take a look

The questions you ask prove that you don't have a good brain.

Of course, as long as the spirit is good, the brain will be flexible, and you should get enough sleep every day, so that the brain can be in good spirits.

Some people worry that "overuse of the brain" will damage physical health and even shorten life expectancy. In fact, there is no scientific basis for this concern. On the contrary, the human brain becomes more and more flexible the more you use it.

A scientist in the United States has pointed out that if an ordinary person can always be a tireless learner, then his brain will store 50 times as many books in his life as the Library of Congress (and the library has about 200 million books). It can be seen that the human brain has an amazing ability to store information. However, due to the influence of various factors, even the people with the best memory have not yet reached this amount of memory1.

The human cerebral cortex has a total of about 14 billion nerve cells, while the average person only uses about 1 billion in a lifetime. In other words, a large part of the human brain's potential remains untapped. After the age of 30, the number of nerve cells in the brain gradually decreases at a rate of more than 100,000 per day.

The same applies to the human brain. Brain nerve cells, like other tissues and organs, can maintain their vitality the more they are used. If you don't use it, the rate of nerve cell reduction will accelerate.

Therefore, if you use your brain diligently, your brain will always be young; If the mind is lazy, it will be sluggish, and it is easy to develop senile dementia in old age. Survey data show that people who use more brains generally have 50% higher intelligence than lazy people; Older people with higher educational and occupational intelligence are usually much slower and lighter in brain aging and mental decline than those with less intellectual activity.

It is obtained by 10 a = 200 and 10 b = 1 5.

10 a 10 b = 10 (a-b) = 200 slag (1 5) = 1000 = 10 3

So a-b=3

Solution: 4 a 2 2b=4 a 4 b=4 (a-b)=4 3=64 If you help you solve the problem, please choose the satisfactory answer, thank you!
