What is \( 2^3 + 2^2 \)?

What is \( 2^3 + 2^2 \)?

• A. 10
• B. 12
• C. 14
• D. 16

Answer: (B)

To solve the expression \( 2^3 + 2^2 \), it's essential to evaluate each power of 2 separately first. Starting with \( 2^3 \): \[ 2^3 = 2 \times 2 \times 2 = 8 \] Now, evaluating \( 2^2 \): \[ 2^2 = 2 \times 2 = 4 \] Next, add the results from the two calculations together: \[ 2^3 + 2^2 = 8 + 4 = 12 \] Thus, the final answer to \( 2^3 + 2^2 \) is 12. This confirms that the correct response is indeed 12, illustrating the correct addition of these two powers of 2.

To solve the expression ( 2^3 + 2^2 ), it's essential to evaluate each power of 2 separately first.

Starting with ( 2^3 ):

[

2^3 = 2 \times 2 \times 2 = 8

]

Now, evaluating ( 2^2 ):

[

2^2 = 2 \times 2 = 4

]

Next, add the results from the two calculations together:

[

2^3 + 2^2 = 8 + 4 = 12

]

Thus, the final answer to ( 2^3 + 2^2 ) is 12. This confirms that the correct response is indeed 12, illustrating the correct addition of these two powers of 2.
