I need to show that there exists no non zero real numbers a,b such that the SqRt of a^2 plus b^2 is equal to the CubeRt of a^3 plus b^3... I have been pluggin in everything cant seem to find the right combination !

since a and b are not equal to 0, this is equivalent to :
this is true if and only if and , because both terms in the sum are positive.
