Question

find the cube roots of the following perfect cube using estimation

a) 592704​

Answer 1

Resposta:

84

Explicação passo-a-passo:

We know that numbers with just two algorithms when elevated by 2 result in another number of at most 4 algorithms. As the one mentioned in this case has 6, we can assume that its cubic root will be one in one of 2 digits. Knowing that the cube of 90 is 729000 and the cube of 80 is 512000, the number will be something between these two. By finishing in 4, we can assume that it is 84, because 4^3=64.

Please, mark this as "best answer". I hope I helped you.
