Question

need help to find out cubic roots

Answer 1

Do you mean cube roots?

Answer 2

no the cube root

Answer 3

is there a better way than just getting it close and just guessing

Answer 4

like the cube root of 625 ik the answer but if i did i would just have to guess is there a mathematical w to find the answer

Answer 5

\(\sf\Large\sqrt[3]{a\times a \times a}=\sqrt[3]{a^3}=a\)

Because

\(\sf\Large\sqrt[n]{x^y}=x^\frac{y}{n}\)

So then that means from the first equation I wrote:

\(\sf\Large\sqrt[3]{a^3}=a^\frac{3}{3}=a\)

\(\sf\Large\sqrt[3]{625}=\sqrt[3]{5\times 5 \times 5\times 5}=\sqrt[3]{5^4}=5^\frac{4}{3}=5\times 5^\frac{1}{3}\)

Answer 13
