Giant spider crab are further from the surface the wolf because -800 is farther down than -300 let say the surface is 0 going down is negative you react -300 before -800
The formula of an area of a square:

a - a side
We have 
substitute:

Used:

Answer:
9
Step-by-step explanation:
n=3, a=729
For any odd integer, n ; a will have only one real nth root which will be a positive integer.
Similarly, for any integer, n, that is > 1 ; related by the expression ;
p^n = a ; the nth root of a = p
Therefore,
If n = 3 ; a = 729
p^3 = 729
To obtain the value of p ; take the cube of both sides
(p^3)*1/3 = 729^1/3
p = 9
Hence, the real nth root of 729 is +9 when n = 3
Tell me if the answer is correct and give brainliest heheheh tq :p
