Louise completed the work shown below. (5x3 + 3)2 = (5x3)2 + (3)2 = 25x6 + 9
Determine if Louise’s answer is correct. Explain.

No, Louise is incorrect because using the order of pemdas I know that (5x3+3)2 is 36. I also know that (5x3)2+(3)2 is 36 using the order of pemdas. However the 3rd problem is 25x6+9 and using pemdas I know that this would equal 234 which is not equal to 36 therefore Louise is incorrect.
