Answer: See below
*Note: I was not sure is -4² was -4² or (-4)². I have done the problem both ways. You should see the problem you are supposed to solve by looking at the 2 different equations below.
Explanation:
The problem states -4²+(5-2)(-6). Now, this can be interpreted in another way. The key is the -4². This can also be (-4)². You get a completely different answer. Since the problem seemed like the first option, I will still do it both ways to make sure you can see the difference. If you meant (-4)², then you would still get an explanation.
-4²+(5-2)(-6)
-16+(3)(-6)
-16+(-18)
-34
_________________________________________________________
(-4)²+(5-2)(-6)
16+(3)(-6)
16+(-18)
-2
As you can see, both answers are very different. The -4 matters whether there are parentheses or not.
