(10x)^(-3)
= 1/[(10x)^3]
= 1/[10^3 * x^3]
= 1/(1000x^3)
The final result is 1/(1000x^3), and none of the given choices seem correct. (Option C would be correct if it used round brackets.)
Hope this helps~

19 fiction books
7 nonfiction books
Explanation
x + y = 26............................................. (i)
x – y = 12............................................ (ii)
By adding the two equations, Elliot obtained the result of
2x = 38.
When divided by 2;
x = 19
Therefore, there are 19 fiction books.
Substituting x into equation (i),
x + y = 26 when x = 19
19 + y = 26
y = 26 - 19
= 7
This means there are 7 nonfiction books
The total is 960. By calculating, we reach the conclusion that Udin has a total of 960 ornamental fish based on having 3 buckets, each containing 320 fish.
