In denominator question number first a part why have you multiply 3 X 3 twice I have two doubts regarding this first is if simply 9 is given why didn't you write only nine at once as you have done in the numerator 2 is written only once no powers given so we have written only two in the same way in denominator 9 is given no power is given then why don't you write 9 or why u wrote 3 into 3 is equal to 9 then why only you have taken 3 you can also take 9 ?😊
