(m - n) (m + 4) = ___

sum_(m=1)^(oo)Tan^(-1) ((2m)/(m^(4)+m^(2)+2))=

m^2(m-2)+2m^2(m+3)-6m (m-4) =_

The degree of a monomial (-15) /19l^3m^4n is

If (m_(i),1/(m_(i))),m_(i)gt0,i=1,2,3,4 are four distinct points on a circle, show that m_(1)m_(2)m_(3)m_(4)=1 .

Problem solving : 4(m+3)=18 , then m=

The solution of the equation 4(m+3) =18 is m=

If m_(1),m_(2), m_(3), m_(4) are respetively the magnitudes of the vectors overset(-)(a_(1))=2overset(-)i-overset(-)j+overset(-)k, overset(-)(a_(2))=3overset(-)i-4overset(-)j-4overset(-)k, overset(-)(a_(3))=-overset(-)I +overset(-)j-overset(-)k, overset(-)(a_(4))=-overset(-)i+3overset(-)j+overset(-)k , then the correct order of m_(1), m_(2), m_(3), m_(4) is
