Thank you for the opportunity to help you with your question!

Original eqn: - (m^4x^5)/k^5 + (2m^2x^5)/(k^5m^-2) -(3m^3x^2k)/(m^-4x^3k^4)

find a common denominator - in this case, k^5. so multiply the second term by (m^2/m^2) which is just multiplying by 1! multiply the third term by (m^4x^-3)/(m^4x^-3), again just multiplying by 1

-(m^4)x^5)/k^5 + (2m^4x^5)/k^5 - (3m^7x^-1k^2)/k^5

now add all the terms

total = (-m^4x^5 + 2m^4x^5 - 3m^7x^-1k^2)/k^5

now group together all the terms you can, pulling out the m^4 term an x^-1 term

(m^4)/(k^5x) (2x^6 -x^6 -3m^3k^2)

no do the subtraction that you can in that messy part

(m^4)(x^6 - 3m^3k^2)/(k^5x)

that's about as far as you can simplify it



Please let me know if you need any clarification. I'm always happy to answer your questions.
