Maybe the answer is -4 ....? I just can't find any more logic to this problem.
Answer:
Step-by-step explanation:
1. A square has four sides and all the sides have equal length.
2. Keeping this on mind, you must multply the lenght given in the problem by 4, as you can see below:
3. Therefore, the polynomial expresion that represents the perimeter of the square is .
This reduces nicely if you first notice that 16/81 = (2/3)^4.
Then use the properties of powers (of positive real numbers):
(16/81)^(3/4) = ((2/3)^4)^(3/4) = (2/3)^3 = 8/27
