Answer 2

$\huge\mathfrak\orange{Answer:}$

b) A perfect cube does not end with 2 zeroes. The given statement is false. So, there are perfect cubes like 8 and 1728 that end with 8. So, the cube of a two digit number cannot be a 3 digit number.

d) False. There are many cubes which will end with 8. The cubes of all the numbers having their unit place digit as 2 will end with 8. The cube of 12 is 1728 and the cube of 22 is 10648.

So, b and d option is false
