Write true or false: No cube can end with exactly two zeros
Determine the statement.
For every zero at the end a number that when cubed gives three zeros at the end.
Hence, the given statement is “true”.
Question 2(ii)
State True or False. A perfect cube does not end with two zeroes.
Write true (T)I or false (f) for the followiong statements: (i) 392 is a perfect cube. (ii) 8640 is not a perfect cube. (iii) No cube can end with exactly two zeros. (iv) There is no perfect cube which ends in 4. (v) For an integer a,a3 is always greater than a2 (vi) if a and b are integers such that a2>b2,thena3>b3 (vii) If a adivides b, then a3 divides b3 (viii) If a2 ends in 9 then a3 ends in 7. (ix) If a2 ends in 5, then a3 ends in 25. (x) If a2 ends in an even number of zeros. than a3 ends in an odd number of zeros.
(ii) A perfect cube does not end with two zeros.
(iii) If square of a number ends with 5, then its cube ends with 25.
(iv) There is no perfect cube which ends with 8.
(v) The cube of a two digit number may be a three digit number.
(vi) The cube of a two digit number may have seven or more digits.
(vii) The cube of a single digit number may be a single digit number.
If a square ends with even number of zeros then a cube ends in odd number of zeros true or false
