​

Answer 1

Answer:

remember for this cube root formula.

The given number should be perfect two digit cube.

Remember cubes of 1 to 10 numbers.

As per the cubes identify as follow as below table.

13 = 1 If last digit of perfect cube number =1, last digit of cube root for that number=1

23 = 8 If last digit of perfect cube number =8, last digit of cube root for that number=2

33 = 27 If last digit of perfect cube number =7, last digit of cube root for that number=3

43 = 64 If last digit of perfect cube number =4, last digit of cube root for that number=4

53 = 125 If last digit of perfect cube number =5, last digit of cube root for that number=5

63 = 216 If last digit of perfect cube number =6, last digit of cube root for that number=6

73 = 343 If last digit of perfect cube number =3, last digit of cube root for that number=7

83 =512 If last digit of perfect cube number =2, last digit of cube root for that number=8

93 = 729 If last digit of perfect cube number =9, last digit of cube root for that number=9

103 = 1000 If last digit of perfect cube number =0, last digit of cube root for that
