Answer 1

Answer:

Step-by-step explanation:

68,600 = 686*10*10

= 686*2*2*5*5

= 343 * (2^3) * (5^2) And if we try dividing 343 by 7, we get 49 or (7^2)

= (2^3) * (5^2) * 7*(7^2)

= (2^3) * (5^2) * (7^3)

Ok. 2 and 7 are cubed, but 5 is only squared, so 68,600 is NOT a perfect cube.

However, if we multiply it by 5, it will become

(2^3) * (5^3) * (7^3) or 343,000 which is a perfect cube.
