Distribute it
42+49i+42i+49^2 (i^2=-1)
49i^2+91i+42
-49+91i+42
It equal to -7+91i
You would approximate because the hypotenuse might not be a perfect square.

Answer:
Step-by-step explanation:
When you have exponents above a like term and they are being multiplied together, you add them.
For example:
So let's group like terms in the numerator:
We can add terms like in the example.
Let's rearrange the denominator.
Now we have:
Cancel like terms
4/8 = 1/2
= 1 So it cancels
= s Since s is raised to the -1 it goes on top and becomes s.
Now we combine everything back together:
