Step-by-step explanation: Use the formula: 
Remember
should always be the hypotenuse or the longest side.
---> evaluate the exponents
----> subtract 12544 to the other side
---> take the square root of both sides

92631
thats the answerrrrrrrrrrrrrrrrrrrr
The 4 on the left side is 10x more than the 4 on the right. This only works if the numbers are next to each other and are the same.
