If the sum of two numbers is known, which of the following is NOT
sufficient to determine the value of the two numbers?
a) One number is greater than the other
b) the cube of one number is 8
c) the product of the two numbers is 8
d) the difference between the two numbers is 2
e) one number is half the other
這題不是只知道兩個數的總合，我怎麼覺得每個選項都無法確定@@
能不能請知道的解釋一下~~讓我知道我的盲點在哪
謝謝!!
