To determine whether a cause-effect relationship exists between two variables, a researcher must use an experimental approach.
<h3>What is
cause-effect relationship?</h3>
A cause-and-effect relationship is one which satisfies some conditions like:
- two events occur at the same time and in the same place
- one event immediately precedes the other
Therefore, To determine whether a cause-effect relationship exists between two variables, a researcher must use an experimental approach.

Answer:
(2xy)³
Step-by-step explanation:
According to the Power Rule of Exponents:

We can apply the Power Rule of Exponents to the given exponential expression, 8x³y³, by taking the smallest factor that when cubed (or raised to an exponent of 3), will produce the same results as the original exponential expression.
8 is a perfect cube of 2: ⇒ 2 × 2 × 2 = 2³ = 8
The cube of x is x³: ⇒ x × x × x = x³
The cube of y is y³ ⇒ y × y × y = y³
Hence, we can take the least common factors, (2xy) and raise them to the third power:
(2xy)³ = 2³x³y³ = 8x³y³
Therefore, the correct answer is: (2xy)³
None of These
Step-by-step explanation:
It is none of these because you'd have to do 20 times 8 which is 160 but that's not one of the choices somit is None of These
