In this case, we will have to move the decimal point 4 spaces to our right, which would mean our exponent would be negative. The number of decimal spaces we moved to our right would be the value of our exponent, which is -4 in this case.
Thus, we have:

Yes it is (10x-y)^2 is the answer of it
It would be 455 inches because you divide 5/2 and it is 2.5 then you multiply it by 182 which is 455
