ab/m ( -2m^(-2) / ba + 3m / a^(-1) b )

than

ab/m (-2/abm^(2) + 3am/b) < handle negative exponents

ab/m * -2/abm^2 + ab/m * 3am/b < distribute

now i have to do......

Kiran,

If the question was simplifying the expression

ab/m ( -2m^(-2) / ba + 3m / a^(-1) b ),

the steps would be

ab/m ( -2m^(-2) / ba + 3m / a^(-1) b )

= ab/m[-2/bam²+3am/b]

=[-2ab/bam³+3a²bm/bm]

=-2/m³+3a²

(Cancelling the common factors in the numberators and the denominators)

-2/m³+3a² cannot be simplified any further.
