Primitive funktion

Need a little help here... :P

what is the primitive funktion of:

$(0,5x^2)^2$

and what is the way of finding it?

Best regards

I don't understand the equation you wrote down...

The primitive function is the antiderivative.

So if the function were $(5x^2)^2=25x^4$

then the primitive function is $5x^5$ because when you take its derivative, you get $25x^4$

aha, it was the outer square of the equation that had me dazzled.

the equation was: $((x^2)/2)^2$

so that correct answer should be:
$0,05x^5$ ?

Thanx for the quick reply by the way

The answer would be $\frac{x^5}{20}+C$

the C is necessary because its some unknown constant.

Not in this case ;)

I was looking for the primitiv form in a integral so the C is not necessery this time :)

Thank you for the help!
Really appreciate it
