Which statement describes what these four powers have in common?
abruzzese [7]

Answer:

"All the powers have a value of 1 because the exponent is 0"

Step-by-step explanation:

To answer this, we need to recall the property that "ANYTHING to the power 0 is ALWAYS equal to 1" (except 0^0).

Here, we see that the base of all of the 4 choices are integers (and NOT ZERO) and all of them are raised to 0th power. So all of them are EQUAL TO 1.

Hence, the correct answer is "All the powers have a value of 1 because the exponent is 0"
