Answer:

D.17

Explanation:

To evaluate the expression 2³ + 3², we first calculate the exponentiation values and then perform the addition.

2³ means 2 raised to the power of 3, which is 2 × 2 × 2 = 8.

3² means 3 raised to the power of 2, which is 3 × 3 = 9.

Now, we can substitute these values back into the expression:

2³ + 3² = 8 + 9 = 17

Therefore, 2³ + 3² equals 17.

The expression simplifies to:

⇨ 17

Work/Explanation:

First, we need to evaluate 2³ : 2 × 2 × 2 = 8

Then we evaluate 3³ : 3 × 3 = 9

And now we add: 8 + 9 = 17

Why did I do exponents first?

Because that's the right order of operations, according to PEMDAS.

where:

  • P = Parentheses
  • E = Exponents
  • M = Multiplication
  • D = Division
  • A = Addition
  • S = Subtraction

Hence, the answer is D.
