Question 985153: "find the smallest whole number that should be multiplied to each of the following so that the product is a square number? a)48 b)54 c)108 d)150 Answer by solver91311(24713) (Show Source):
In order to be a perfect square, all prime factors of a number must be represented an even number of times.
The prime factorization of 48 is . You have an even number of factors of 2, but only 1 factor of 3. If you include another factor of 3, then there will be four 2s and two 3s, which results in 48 times 3 or 144. 144 is indeed a perfect square.
