Answer:
[(4c)-(4c)a]
Step-by-step explanation:
first write the question like
a^3+8b^3+64c^3-24abc
second step
a^3+(2b)^3+(4c)^3(a)(2b)(4c)
{here 8b ^3 has becomed 2b ^3 becaue 2×2×2 =8 and next so .}
third step
(a+2b+4c)[a^2+(2b)^2+(4c)^2-a(2b)-(2b)
[(4c)-(4c)a]
note =after this ^ signe the number is given is root .
