Question

is 68600 a perfect cube if not find the smallest number by which 68600 must be multiplied to get a perfect cube also find cube root of the new perfect cube so obtained ​

Answer 1

Answer:

Step-by-step explanation:

68600=2*2*2*5*5*7*7*7

So 68600 is not a perfect cube

So we have to multiple 5 to get get perfect cube then we will get 343000

Answer 2

Step-by-step explanation:

we see that

68600=2×2×2×5×5×7×7×7

since 5 don't occur in triplets

therefore 68600 is not a perfect cube

so, we multiply 5 with 68600 to make it a perfect cube

68600×5=343000

343000=70³
