URGENTE OBRIGADO !

Answer 1

A) 6t-4t-2t ==> 0

B)0,5m²-m² ==> 0,5m²

C)a/2-2a/3==> a  - 2a==> 3a-4a==> - 2a==> - a
                      2     3           6             6          3

D)(4p²).(-6p³)==> -24p^5

E)-x²y.y²==> -x^2.y^3

F)(-8a²c).(-6ac)==> 8a^2c==> 4a
                             6ac          3

G)14m²:7m ==> 2m

H)(-3x²y)³==> - 27x^6y^3

I)(-0,5mn²)² ==> 0,25m^2n^4
