Answer 1

Answer:

ANSWER

First we have to take some first multiples of 972

it's long process

972, 1944, 2916, 3888, 4860, 5832, 6804, 7776, 8748, 9720

we will keep aa nos. under root

972 under root is not a perfect square

1944 is not a perfect square

2916 is = 54²

so, 2916 / 972 = 3

so we should multiply 972 × 3 to get a perfect sqr
