Answer:
The answer is correct, it'll be xyz.
Step-by-step explanation:
See there 5 root, so they just remove the root and keep it as 1/5 on power. Now they are just multiplying 1/5 to each variables' power, like 20*1/5 , -10*1/5, 5*1/5. And after that they are just writing the value of power after calculation like 20*1/5 is 4. Till here, there was no change at the last term that is x^3/y^3. (^ this sign denotes to the power of). And after that they are again calculating the powers. As x^3 was there as denominator, they are doing substraction and as y^3 was there as numerator, they are doing addition. Now again they are calculating. Like 4-3=1, -2+3= 1. And we don't write the power of 1 , we just write the variable, like they did and the answer is *xyz*.
Hope it helps you
