just find the LCM of the denominators and they will be the denominators,but remember that nominator is also needed to be timed larger
in fact,this question is to calculate,and not just simplify. (-19)^2 =19^2 =(10+9)^2 =10^2+2(9)(10)+9^2 =100+180+81 =361 in this question,we can see that there is no need to calculate the answer by using CALCULATOR
