Schrijf als x^3=9x√x 8 (ik vermoed dat 8 mee onder de wortel staat???)


Schrijf de wortelvorm met x met rationale exponenten: x^(3/2)))en deel beide leden door deze wortelvorm, zodat de vergelijking van de vorm wordt: x^(a) = b, waaruit x=b^(1/a)

die exponent van x wordt x^3/x^(3/2)=x^(3/2)

"x^3-9x√x 8=0"

Okay, that is an equation.

And what is your question???

The question is indeed not GeoGebra related. A student could'nt solve (manually) an equation and supposed she would find some math help in this pages.

So I could respond that this is not a math help page for students, but in the same time I had typed how to cope with the problem and I chose this second option
