Problem 309
Describe if the statement is true or false, and tell why.
a. 7 │ 23
b. 24 is a factor of 8.
c. 16 │ 16
d. 0 │ 6
e. 15 │ 0
f. 65 is a multiple of 15.
g. n3 is a divisor if n5.
h. A number is always a factor of its square.
Solution
a. False , both are prime numbers so we can’t get 23 by multiply any other number to 7
b. False, 24 can’t be factor of 8,factors can’t be more than the number itself.
c. True, if we multiply 16 by 1 we get 16
d. False, multiply by zero we get always zero.
e. True, if we multiply 15 by 0 we get result zero.
f. False, 15 is not the factor of 65.
g. True, n5 is completely divisible by n3
h. True, since nxn=n2.
