Divide `25m^4 n^3 o^2` by `5m^2n^2o^2`

If m = 3 and n = 2 find the value of 2m^3 +3n^2- 5 m^2n

Factorise : 4m^(3)n^(2) +12 m^(2)n^(2)+18 m^(4)n^(3)

Divide the first algebraic expression by the second algebraic expression in the pairs of algebraic numbers: m^2n^4+m^3n^3-m^4n^2 , -m^4n^4 ,

3.If m o* n are positive integers such that m^(2)+2n=n^(2)+2m+5, then the value of n is

5m -n = 3m+4n then find the value of the expressions: (m^2+n^2)/(m^2-n^2)

Multiply the binomials. (2.5m - 0.5n) and (2.5 m + 0.5n)

Add: 5m – 7n, 3n – 4m + 2, 2m – 3mn – 5
