tolong jawaban dan pembahasan
terima kasih

Answer 1

(5m+3)^44
= (5m+3)(5m+3)(5m+3)(5m+3)
= (25m^2+30m+9)(25m^2+30m+9)
= 625m^4+750m^3+225m^2+750m^3+900m^2+270m+225m^2+270m+81
= 625m^4+1500m^3+1350m^2+540m+81

(2m-5)^4
= (2m-5)(2m-5)(2m-5)(2m-5)
= (4m^2-20m+25)(4m^2-10m+25)
= 16m^4-40m^3+100m^2-80m^3+200m^2-500m+100m^2-250m+625
= 16m^4-120m^3+400m^2-750m+625

semoga membantu :)
