Let's call this number b
42000 = 24 x 3 x 53 x 7
We have 42000 x b = a2 and a is an integer
Then a = sqrt(42000 x b) = sqrt(b) x sqrt(24 x 3 x 53 x 7)
sqrt(24 x 3 x 53 x 7) = 22 x sqrt(3) x 5 x sqrt(5) x sqrt(7)
For a to be an integer sqrt(b) must be sqrt(3) x sqrt(5) x sqrt(7) at least
Thus b = 105

15*2940 = 44100 and the square root of this is 210
find the smallest number by which 9408 must be multiplied to get a perfect square/ also find the square of the number
38
your answer is 3 147 * 3 = 441 21 * 21 = 441

Square number.
15*2940 = 44100 and the square root of this is 210
find the smallest number by which 9408 must be multiplied to get a perfect square/ also find the square of the number
55

A square number is the result of a number multiplied by itself. 3 x 3 = 9 9 is a square number.
your answer is 3 147 * 3 = 441 21 * 21 = 441
How about 150*6 = 900 which is a perfect square because 30*30 = 900
32 is the smallest two-digit number that can be multiplied by itself to give a four-digit number. (32x32)=1024
Times it again by the same number [e.g] square of 4 is 4X4=16 so square of 4 is 16
The smallest square number qreater than 1 is 2. * * * * * 2 is not a perfect square number.
