Differentiate the following: sqrt[10/(4+x)]

In summary, the conversation is about differentiating the expression sqrt[10/(4+x)] using the chain rule. The speaker re-writes the expression as [10(4+x)^-1]^1/2 but is unsure how to include the sqrt in the differentiation process. They then ask for help with the derivatives of u^-1/2 and v^-1.

i need to differentiate the following:

sqrt[10/(4+x)]

so i re-wrote it as:

[10(4+x)^-1]^1/2

but am getting very confused when i try to differentiate it.

any help would be great! cheers

Could you show your attempt at differentiating the expression?

Step by step using the chain rule
What is the derivative of u-1/2?

What is the derivative of v-1?

well first i differentiated 10(4+x)^-1
which is -10(4+x)^-2

but i don't know how to include the sqrt...
 

What is the square root of 10 divided by 4 plus x?

The square root of 10 divided by 4 plus x can be expressed as sqrt[10/(4+x)].

How do I differentiate the expression sqrt[10/(4+x)]?

To differentiate sqrt[10/(4+x)], we first rewrite the expression as (10/(4+x))^(1/2) and then use the power rule of differentiation to get (1/2)(10/(4+x))^(-1/2)(10/(4+x))', which simplifies to -5/(4+x)^2.

Can the expression sqrt[10/(4+x)] be simplified?

Yes, the expression sqrt[10/(4+x)] can be simplified to (2*sqrt[10])/sqrt(4+x).

What is the domain of sqrt[10/(4+x)]?

The domain of sqrt[10/(4+x)] is all real numbers except -4, as (4+x) cannot be equal to 0.

How does the value of x affect the value of sqrt[10/(4+x)]?

The value of x affects the value of sqrt[10/(4+x)] by changing the denominator (4+x). As x increases, the denominator increases and the value of the expression decreases. As x decreases, the denominator decreases and the value of the expression increases.
