a=0.00...0125,52个0,b=0.00...08,48个0.求a×b
a=0.00...0125,52个0,b=0.00...08,48个0.求a×b
a=0.00.0125(1984个0),b=0.00.08(1988个0)试求:a+b,a-b,a*b,a/b
已知a=0.00...(2000个0)0125,b=0.00...(2004个0)08,求:a+b,b-a.
a=0.00.0125(1996个0), b=0.00.08(1996个0),求a×b,a÷b,a+b
a=0.00...0125(2002个0),b=0.00...08(2004个0) 求(1)a+b=?(2)a*b=?
a=0.00.0125(1996个0),b=0.00.08(2000个0)试求:a*b,a/b
a=0.00...0125 b=8000...0 a,b都是50个0 求a*b
a=0.00.0125;b=0.00.08,求a+b,a-b (190个零) (191个零)
数学题,A=0.00.0(2000个)0125,B=0.00...0(2004个).0,8,求A+B,A-B,求解,
设a=0.00...0125=9个0,b=0.00...08=10个0,求a/b是多少?明天就要交作业,急家急
a=0.00……0125(有1996个0) b=0.00……08(有2000个0)a+b= a-b= a*b= a/b=
若a=0.00...025里面有2002个0,b=0.00...04里面有2003个0,求:a+b=().a一b=( )
