`A = B^n C^m`
Where `A = LT` ; `B = L^2T^-1` and `C= LT^2`
Arrange the equation first by substituting the terms given.
`[L][T] = ([L]^2 [T]^-1)^n ([L] [T]^2)^m`
`[L][T] = [L]^(2n+m) [T]^(-n + 2m)`
eq 1 -> `1 = 2n + m` --> `1 = 2n + m`
eq 2 -> `(1 = -n+ 2m)*2` --> `2 = -2n + 4m` add
-------------------
`3 = 5m`
`m = 3/5`
substitute `m = 3/5` to any of the two equations.
eq 1-> `1 = 2n + m`
`1 = 2n + (3/5)`
`1 -3/5 = 2n`
`2/5 = 2n`
`n = 1/5`
Therefore the values of n and m are 1/5 and 3/5 respectively.
