if you answer correct I will make you brainlist ​

Answer 1

• 8 * 8 * 8 = 512. So, cube root of 512 is 8

• The symbol used to denote the cube root is ∛ For example: ∛2197 = ∛(13 * 13 * 13) = 13. As 2197 is a perfect cube, it is easy to determine the cube root of 2197. Hence, the cube root of 2197 is 13.

• If any number is ending with 5 , then its cube root's Digit must be ending in 5 only . The minimum number is1 , Hence the cube root of 3375 is15.

• Cut the last three numbers from the left of the number whose cube is to be found and then for the remaining numbers figure out the number whose cube is closest to that number. Last digit is 2 so we have to replace 2 with 8 thus now we have 8, Thus the unit place of the cube root of 5832 is 8.
