B = 3a/(a-4)，a >； 4. Then, by using the basic inequality, we can get
Solution: Because 3a+4b >；; 0, ab> This is a detailed answer. Have a look/exercise/math /804633.
If log4(3a+4b)=log2 (radical ab), then the minimum value of a+b is ().
A radical number 3 of 6+2? B 7+2 root number 3? C 6+4 root number 3? D 7+4 root number 3
It is difficult to understand this topic. I believe you will understand after reading the answer. If you don't understand, you can keep asking me. This is where my classmates told me to study. It's quite useful. If it helps, I hope to adopt it! Come on ~ I wish you progress in your study!
