1. ## Integration Problem

Integrate:
$
6(e^{4-3x})^2
$

Is it correct if i do this: $6(e^{8-6x})$ and then solve?

and then let u = 8-6x and du=-6

then the answer comes to $-e^{8-6x} + C$

2. Hello,

It's all correct

3. thank you, here is another one (I have a test on Friday so I'm trying to do as many problems as I can)

Integrate: $\frac{3}{4}-\frac{1}{\sqrt{6x}}$

I let u = 6x and du = 6dx

the answer I end up with is:
$

-\frac{1}{4}\sqrt{6x}+C
$

4. Hello,

And what about integrating the constant ? The integral of 1 is x, the integral of 3/4 will be...

But according to your answer, would the integral rather be $\int \frac 34\times \frac{1}{\sqrt{6x}} ~dx$ ? In which case, it's correct - again

5. oops no you were right I did it wrong but thanks for pointing that out
