Question

what is the value of the expression 9 - 2 x 2 + 6 x 4^2

Answer 1

To evaluate the expression 9 - 2 x 2 + 6 x 4^2, follow the order of operations (also known as PEMDAS/BODMAS):

First, calculate the exponent:
4^2 = 4 x 4 = 16

Then, perform the multiplication:
6 x 16 = 96

Next, perform the remaining multiplication:
2 x 2 = 4

Now, perform the addition and subtraction from left to right:
9 - 4 + 96 = 105

Therefore, the value of the expression 9 - 2 x 2 + 6 x 4^2 is 105.
