Of course you can use the quotient rule, but it is usually not the easiest method. If we do use it here, we get $${d\over dx}{10\over x^2}={x^2\cdot 0-10\cdot 2x\over x^4}= {-20\over x^3},$$ since the derivative of 10 is 0.
1 Young children can't tell the difference between fantasy and reality. 2  Your preschooler's rich imagination is a big part of his normal development, but that means it is usually hard for him to tell the difference between what's real and what's imaginary.
I feel it is just as important to discuss the real world as it is to have young people, even children, read about dystopian themes so they can become active in changing the world. I agree that reading these fantasy novels is a way to escape and to see heroic efforts to fight injustice, evil, greed, etc.his is an authorâs perspective of their novel. And why they let their kids read dystopian novels. I do not know if the novel is any good, the reasoning is ok, even if it is unlikely global warming will make Earth average 115 degree days.
