What is the small

Answer :

(i) 675


Factors of 675 = 3 × 3 × 3 × 5 × 5 = 33 × 52


Hence, to make a perfect cube we need to multiply the product by 5.


(ii) 1323


Factors of 1323 = 3 × 3 × 3 × 7 × 7 = 33 × 72


Hence, to make a perfect cube we need to multiply the product by 7.


(iii) 2560


Factors of 2560 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 5 = 23 × 23 × 23 × 5


Hence, to make a perfect cube we need to multiply the product by 5 × 5 = 25.


(iv) 7803


Factors of 7803 = 3 × 3 × 3 × 17 × 17 = 33 × 172


Hence, to make a perfect cube we need to multiply the product by 17.


(v) 107811


Factors of 107811 = 3 × 3 × 3 × 3 × 11 × 11 × 11 = 33 × 3 × 113


Hence, to make a perfect cube we need to multiply the product by 3 × 3 = 9.


(vi) 35721


Factors of 35721 = 3 × 3 × 3 × 3 × 3 × 3 × 7 × 7 = 33 × 33 × 72
