In the expression, the real number a equals 12 and the real number b equals -16.
<h3>How to explain the information?</h3>
It should be noted that the expression given is:
= (4 - 2i)²
Therefore, we need to expand the expression. This will be:
= (4 - 2i)(4 - 2i)
= 16 -8i -8i + 4i²
= 16 -16i +4i²
Substitute -1 for i²
= 16 - 16i + 4(-1)
= 16 - 16i - 4
= 12 - 16i
Therefore, the value of the expression is 12 - 16i.

Therefore,
<span>1. </span><span>A penny weighs about 0.1 oz.
Now, we need to find the weights of pennies in pounds
=> always remember that in every 1 oz, there is 0.0625 pounds.
Since 0.1 is 1/10 of 1 oz, we need to find the value of it in pounds.
=> 0.0625 pounds / 10
=> 0.0625 pounds.
Therefore, in 0.1 oz of penny is
equivalent to 0.00625 pounds.
In problem like this, before determining the answer, you need to make sure that
both unit of measurements are the same. If not, then try to convert.</span>
