WebSo the answer, this part right over here, is just going to simplify to 8. And so our answer to this, the cube root of negative 512, is negative 8. And we are done. And you could verify … WebWe can think graphs of absolute value and quadratic functions as transformations of the parent functions x and x². Importantly, we can extend this idea to include transformations of any function whatsoever! This fascinating concept allows us to graph many other types of functions, like square/cube root, exponential and logarithmic functions.

So if you are asking (-.5)^ (1/5) we could write the square root sign with a raised 5 on the crook of the root sign, and a -.5 inside. Hope this helps. ( 5 votes) Icedlatte 6 years ago
WebIn the "into to cube roots" video Sal showed how doing the prime factorization of a number can help you figure out its cube root. Take 64 which can break down into 4x16; 16 breaks down into 4x4; so if you multiply 4x4x4 you get 64. Take 0.125 which can break down into .5x.25; .25 breaks down into .5x.5; so if you multiply .5x.5x.5 you get .125 WebLearn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more.
