Done the first few steps but got a bit lost rn

#

a^5 = 243/32

#

a = 3/2

#

Also

#

Letting u = 3/2

#

(3/2 - kx^m)^n = 243/32 - 405/4x ^ u + 540x^2u - 1440x^3u + px^4u -qx^5u

#

this is as far as i got and dont know what to do to progress further, any help is appreciated

What do u think n would be

#

Look at the amount of terms

#

Oh yeh n is 5

#

I forgot to say that but i used it to work out a

#

And now i see that m must be 3/2 because of the increments shown
