Answer:

$\Large{\underline{\underline{\sf{\red{Req}\pink{uir}\green{ed}\:\purple{Ans}\blue{wer}\:\orange{:-}}}}}$

:⟼ step one :

make two groups right to left

first group=683

:⟼ second group=19

step two: first group 683 unit digit is 3 so

unit digit of cube root will be 7

:⟼ step three :

second group lies between 19

(2³ =8 ) and 3³=7

so take the smaller number 2 as ten's place

therefore ,

cube root is 19683 =27

I hope it is helpful
