动作
无聊
8*b=8b a-8b=?
=SUMPRODUCT(($B$3:$B$8>$B3)/COUNTIF($B$3:$B$8,$B$3:$B$8))+1这个excel
2b(8b-2b+3)-3b的平方(5b-1),b=-1
A=B+B+B+B+B+B+B+B+B+B+B+B+B+B+B A-B×3=C C+2×7+2=1A=B+B+B+B+B+B+B+B+B+B+B+B+B+B+BA-B×3=CC+2×7+2=148148-(C-32)=DA,B,C,D各是多少?
b=(8,6)
已知|a|=6,|b|=8,且|a+b|=|a-b|,求|a-b|.
已知|a|=6 |b|=8,且|a+b|= |a-b| 求|a-b|
已知|a|=6 |b|=8,且|a+b|= |a-b| 求|a-b|
1KB=1024B.1kb=1024b 1B=8b?
a×a+ab=18,ab+b×b=8,则a×a-b×b=
解方程组:9(a+b)+(a-b)=25,2(a+b)-(a-b)=8
已知:a+b=-8,ab=12,b*√(b/a)+a*√(a/b)
a^+b^-6a-8b+25=0,求b/a-a/b
已知向量a ,b满足|a|=6,|b|=8,则|a+b|=|a-b|,求|a+b|
已知a+b=-8;[a+b][a-b]=16求a.a-ab+b.b的值
已知a*a+b*b-6a-8b+25=0,求b/a-a/b的值
3(a-b)的平方-7(a-b)+8(a-b)的平方+6(a-b) a-b=2
a >1,b >0,a ^b +a ^-b =8^1/2,a ^b -a ^-b得几
