Answer:
Step-by-step explanation:
PEDMAS stands for
Parentheses (brackerts
Exponents (squared, squared roots, powers)
Divide and Multiply from left to right
Add and Subtract from left to right
This means in this case that we first look at everything inside the brackets and at the end multiply by 7. The inside of the brackets says -25 + 4². In PEDMAS, the E (exponent) comes before A (add), so we do 4² first and then we do the -25. This results in:
-25 + 4² =
-25 + 16 =
-9
So now we are left with (-9) x 7
This is just a multiplication which gives us -63.
I hope this helps!
