Hello! I am struggling with this question can anyone help me and check my answer?
Evaluate using the order of operations:
4 to the power of 2 + 7 - 2
A. 13
B. 21 (my answer)
C. 32
D. 69
Thank you :>
If you mean 2 with 4 as an exponent, you are correct its 21. 2^4=16 16+7=23 23-2=21

How I got my answer:
4 x 4 = 16 + 7 = 23 - 2 = 21
Thank you Yolo
Also it's actually 4 Squared + 7 - 2 = 21 :>
Hello! I'd be happy to help you with this question. To evaluate the expression using the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), you need to follow the correct order of operations.
First, you need to calculate the exponent, which means you need to calculate 4 raised to the power of 2.
4 to the power of 2 means 4 multiplied by itself: 4 * 4 = 16.
Now, you can substitute the result of the exponent in place of 4 to the power of 2 in the original expression:
16 + 7 - 2 = 23 - 2 = 21.
So, the correct answer is B. 21, which matches with your answer.
Well done! Your answer is correct.
