Big Brothers and Big Sisters, help me if you know 10

Follow the steps below to see if it still doesn't work you can hi me:

1. Uninstall the audio driver in Device Manager and then scan the installation again.

3. If the system has ghost (one-click restore), restore the system, if there is no ghost and turn on the system restore function, restore the disk where the system is located to an earlier (that is, the normal time limit of the system you know) time.

4. It is really not possible to reinstall the system, because reinstalling the system will lose the file of the drive letter where the system is located, and sometimes try not to reinstall the system, it is said that there will be damage to the hard disk!

It's best to reinstall the system once! It can be solved by running slowly, and the audio part can be played, and the part can not be played, which is also a difficult problem to solve, so it is the best way to force the redo system to save time and effort.

This happened to my computer a few days ago, I asked some people, they said that there was no antivirus software installed in my computer, and there were viruses in some files, and then I checked it from the Internet, and it was related to the small speaker on the computer. Try it if you don't have to.

I can help you solve the problem that the little speaker doesn't have.,The next volume control program,Put it in C:Windows system32 and solve it.。

1≠0 again a appears in the denominator, so a ≠ 0

Then it can only be a+b=0

a=-bb/a=-1≠1

So b=1a=-1

a^2010+b^2011

If a=0 then b a is meaningless.

So a+b=0 then b a=-1 so a=-1 b=1

In the second week, the project was completed 60 meters less than half, so 320 + 60 = 380 is half, and the total is 380 + 380 = 760

18. = A to the power (2 3 + 3 4-5 6) = A to the power (7 12).

19. =4 (-2 3) A to the (2 3 + 1 3) power of b (-2 3 + 1 3) power.

6ab to the power of (-1 to 3).

20. log3 (3 3 to the 4th power).

log3 to the 7th power of 3.

721, =log2 (log2 2 to the power of 4) = log2 4

log2 2²

222、x-1≠0

x+4>0

x>-4 and x≠1

f(7)=6 (7-1)+ 7+4)=1+ 11f(12)=6 (12-1)+ 12+4)=6 11 +4=4 and 6 11

(1) A triangle is equal to 18 and a circle is equal to 6
