Just substitute the given value into anywhere you see the term x:

2 x 4^2 + 12

Follow the PEMDAS rule:

(calculate the exponential first)

4^2 = 16

Now we have:

2 x 16 + 12

(now the multiplication needs to be calculated)

16 x 2 = 32

Now we have:

32 + 12

Add them together to get the answer:

44 <== this is the answer

Hope This Helps You!

Good Luck (:

Have A Great Day ^-^

Since x=2, the expression would be 2 × 4 to the of 2 + 12.

4 to the power of 2 = 16

2 × 16 = 32

32 + 12 = 44

The answer would be 44.
