Answer:
It is not a perfect cube.
The smallest number by which 243 must be multiplied to be a perfect cube is
3
how we found it?
243 = 3×3×3×3×3
= (3×3×3)×3×3
= 3³×3×3
to make a perfect cube we have to multiply 3 or divide 9 (3×3). But here we have to find answer with multiplication, so answer will be 3.
243×3 = 729
It is a perfect cube.
729 = 3×3×3×3×3×3
= 3³×3³
= 9³
hope it helps.
