435和232
哪裡的題？？？？
2個數，他們的最大公因數是4，最小公倍數是84.這兩個數有可能是（）和（）或（）和（）.
急.
2個數，他們的最大公因數是4，最小公倍數是84.這兩個數有可能是（4）和（84）或（12）和（28）.
對括弧部分提問：Our P.E.teacher needs（12）besketbalol.
How many basketball do your P.E.teacher need？
提問數量，後面跟的是可數名詞，用how many；後面跟不可數名詞，用how much
How many basketballs does our PE teacher need？
1
How many basketballs does your P.E. teacher need？
應該是Basketballs，樓主拼錯了吧
改成疑問句時，our改成your
How many besketballs does your P.E. teacher need？
已知2z=1-（z的共軛複數）^2，求z-√2i
設z = a+bi則z的共軛複數為a-bi
由題意得：2a+2bi = 1-（a-bi）²；
2a+2bi = 1-a²；+2abi+b²；
a²；+2a-b²；-1 +（2b-2ab）i = 0
所以a²；+2a-b²；-1 = 0且2b-2ab=0
故a=1 b=√2
那麼z-√2i = 1+√2i-√2i = 1
The desk in the frout of the classroom is our teacher’s.劃線提問.劃線部分：our teacher’s
Whose desk is in the front of the classroom？
Whose desk in the front of the classroom？
whose desk in the front of the classroom
Whose desk is in the front of the classroom？
Whose is the desk in the front of the classeroom？
設複數=1+√2i，求Z-2Z
z-2z=-z=-1-√2i
-z=-1-√2i；
There is teacher's desk ____ourclassroom.Andthree trees ___our classroom，too.
A.in front of；in front of B.in front of；in the front of
C.in the front of；in front of D.in the front of；in the front of
in the front of（指事物內部）
in front of（指事物外面）都是“在……前面
in，behind
複數1－2i分之5i的虛部怎麼求？我數學很差.
分母實數化，得
5i/1-2i
=[（5i）（1+2i）]/[（1-2i）（1+2i）]
=（-10+5i）/5
=-2+i
所以虛部為1.
What is on the teacher is desk是啥意思
What is on the teacher is desk是啥意思
應該是What is on the teacher's desk？
老師桌子上有什麼？
在老師的書桌上放著什麼？
複數（2i/1+i）^2=？
=（2i）²；/（i+1）²；
=-4/（1+2i-1）
=-4/2i
=-2i/i²；
=2i
（2i/1+i）^2=-4/（2i）=2i
（2i/1+i）^2= [ 2i*（1-i）/（1+1）] ^2 = [ i*（1-i）] ^2 =（1+i）^2 = 1-1+2i = 2i
