simplify 3m^-4 (4m^6-m^5)+(5m)^2 please show work?

Answer 1

Distribute, and use the property (ab)^x = a^x b^x:

12m^(-4)m^6 - 3m^(-4)m^5 + 5^2 m^2

Use a^x a^y = a^(x+y):

12m^2 - 3m + 25m^2

Combine like terms:

37m^2 - 3m

Answer 2

3m^-4 (4m^6-m^5)+(5m)^2=
(3/m^4)(4m^6-m^5)+25m^2=
12(m^6/m^4) - 3(m^5/m^4) + 25m^2=
12m^2 - 3m + 25m^2=
37m^2-3m=
m(37m-3)

i may have made a mistake though

Answer 3

All you do is mulitply and add or subtract the powers depending on there signs.

Answer:

12m^2 -3x +25m^2
37m^2 -3m

Answer 4

was it correctly written????
