I believe this is the correct sub forum
Can you please confirm the problem?

Help, Solve for X
4x^-2/3 = 16
i got to the point where 1/3\sqrt{4x^2} = 16 , then i am totally lost
Also what is the rule for a base with a power of negative fraction? Why do you have to flip ex: x^-1/2. 1/\sqrt{x}
Thank You
PS: am i posting in the corrct subforum？。。.
raising a nonzero number to a "−" power produces its reciprocal...
and
i.e.
think you get the idea...
...taking what you know from above and understanding that the numerator raises the number to that power (in this case ^3) and the denominator takes the root (in this case 2nd root or sqrt) therefore you can simplify...
...This
is the same as this...
is the same as this...
Therefore, we easily solve...
and
Thus you get...
