"设a^2=b^2=m(a>0,b>0),且a+b=6,则m等于"
"设a^2=b^2=m(a>0,b>0),且a+b=6,则m等于"
设2∧a=5∧b=m,且1/a+1b=2,则m等于
设a2=b的四次方=m(a>0,b>0),且a+b=6,则m等于
设a>b>0,m=a+b
设2a=5b=m,且1/b+1/a=2,则m= ?
设2a=5b=m,且1a+1b=2,则m=( )
设2^a=5^b=m,且1\a+1\b=2,则m等于多少(要过程)
a*b=b-a分之a+b,且3*m=2,求m
已知m^a=3,m^b=5,m>0且a+b=2,求m的值
设k是自然数,且ka+b=0,则|a/|b|-1|+||a|/b-2|等于
2^a=5^b=m,且1/a+1/b=2,则m等于
设2∧a=5∧b=m,且1/a+1/b=2,求m
