Final answer:
The cube root of 27 is 3, and substituting this into the expression 2 - ∛27 equals 2 - 3, which simplifies to -1. Thus, the correct answer is D) -1.
Step-by-step explanation:
The question asks which expression is equal to 2 - ∛27. To solve this, we first need to determine what ∛27 is equal to. The cube root of a number is a value that, when multiplied by itself three times, gives the original number. In this case, we are looking for the cube root of 27.
Knowing that 3 × 3 × 3 = 27, we can conclude that ∛27 = 3. Now, we can substitute this value back into the original expression to get:
2 - ∛27 = 2 - 3
This simplifies to:
2 - 3 = -1
Therefore, the expression equal to 2 - ∛27 is -1.
The correct answer to the question is D) -1.
To simplify the expression 2 - ∛27, we can start by finding the cube root of 27. The cube root of 27 is 3, so the expression becomes 2 - 3. Simplifying further, we get -1.
Therefore, the correct expression that is equal to 2 - ∛27 is D) -1.
