Answer 1

hey buddy....
As per the question,
64^{-1/3}(64^{1/3}-64^{2/3}64−1/3(641/3−642/3 
As, 64 = 4^364=43 
(4^3)^{-1/3}((4^3)^{1/3}- (4^3)^{2/3})(43)−1/3((43)1/3−(43)2/3) 

\begin{lgathered}(4^3)^{-1/3}((4^3)^{1/3}- (4^3)^{2/3}) \\ \\ 4^{-1} (4^1 - 4^2) \\ \\ \frac{1}{4}(4-16) \\ \\ \frac{1}{4}(-12) \\ \\\end{lgathered}(43)−1/3((43)1/3−(43)2/3)4−1(41−42)41​(4−16)41​(−12)​ 
-3
The answer is -3.

hope this helps....

please mark my answer as brainlist answer....

Answer 2

As per the question,
$64^{-1/3}(64^{1/3}-64^{2/3}$
As, $64 = 4^3$
$(4^3)^{-1/3}((4^3)^{1/3}- (4^3)^{2/3})$

[tex](4^3)^{-1/3}((4^3)^{1/3}- (4^3)^{2/3}) \\ \\ 4^{-1} (4^1 - 4^2) \\ \\ \frac{1}{4}(4-16) \\ \\ \frac{1}{4}(-12) \\ \\ [/tex]
-3
The answer is -3.
