882=2*3*3*7*7
=2*(3*3)*(7*7)
2 is the only isolated number
therefore
if we multiply 882 with 2 it becomes
a perfect square.
882*2= (2*2)*(3*3)*(3*3)
=(2*3*3)^2
=18^2
if it useful to u select it as brainliast
=2*(3*3)*(7*7)

882= 2×3×3×7×7
2 is only the no which is not in pair so
882 must be multiplied be 2 to make it a perfect square
882×2= 1764
1764=2×2×3×3×7×7
1764= 2×3×7(we take pair of the no.)
1764= 42
1764 is square of 42
