Question

By what smallest number must 180 be multiplied
so that it becomes a perfect square? Also, find the
square root of the number obtained.​

Answer 1

Solution: Let us find the factors of 180

180 = 2*2 * 3*3 *5

We can see that 5 doesn't have a pair, so if we multiple 180 by 5 , we will get a perfect square .i.e (180*5) = 900

The square root of the number obtained is 30 because the obtained number is 900 & its square root is 30
