I will give you a quick lesson.
The formula is a² + b² = c²
The longest line(usually the bottom) is C
If something is squared, multiply it by itself, for example, 6² is 36, multiply 6 by 6(6 x 6).
Do the same thing with a and b.
Then add a and b after you square them.
To make the number smaller, square root it.
Then you will get your answer, don't forget the exponent.
Sorry for not giving you the answer, but I hope this quick lesson helped you, this is how I learned, I hope this makes it easier for you. Have a GOOD DAY!
