Question

the smallest number by which 72 must be divided to make it a perfect square
​

Answer 1

Answer:

⁶

Step-by-step explanation:

DIVIDING 72/2 we get 36 that is a perfect square of 6 andthe smallest one is 2 itself.

Answer 2

Answer:

72 must be divided by 2 in order to get a number which is a perfect square. Therefore, the correct answer would be 2.

Step-by-step explanation:

Given: The number which has to be divided = 72.

To Find: The number by which the given number must be divided in order to attain a perfect square.

Now, 72 is a Composite number. It means it has factors other than 1 and 72 itself.

The factors of 72 are = 2, 3, 4, 6, 8, 9, 12, 18, etc.

Now, we have to find the smallest number by which we can divide 72 to get a perfect square number. Hence, we'll start with 2.

Dividing by 2, we get $\frac{72}{2}$ = 36

Now, 6² = 36 as well, which means dividing 72 by 2 gives us a perfect square number 36, which is the square of 6.

Hence, the correct answer would be 2.
