Answer:


-16

Explanation:


-3 \cdot (7+(-3)^2) / 3

To simplify this expression, use the order of operations (PEMDAS):

P arentheses

E xponents

M ultiplication

D ivision

A ddition

S ubtraction

First, simplify what is in the parentheses.


7 + (-3)^2

Remember that any number squared (
\Box ^2 ) is positive, so:


(-3)^2 = 9

Therefore,


7 + (-3)^2


= 7 + 9


= 16

We can now replace the parentheses in the original expression with 16.


-3 \cdot (7+(-3)^2) / 3


= -3(16) / 3

Finally, simplify by multiplying and dividing.


-3(16) / 3


= -48 / 3


= -16
