1.what is the value of x in the equation x=1+ x/2 + x/4 + x/8 + x/16?
若兩邊同乘16, 不就變成 16x = 16 + 16x 這樣x 能解得出來嗎?
因為答案是16有點想不通...
2. Is m=0
(1)|m| = m
(2)|m| = -m
Answer: C
3. If lines k, m and n are in the same plane, is line m parallel to line n?
(1)Line m is parallel to line k.
(2)Line n is not parallel to line k.
Answer: E
麻煩解說一下，謝謝各位大大~ 感恩~
