c) (2x-3y)^2
d) (4m^5+5n^3)^2
e) (3/6w-1/2y)^2
xfaaaaa ayuda es para mañana​

Answer 1

Respuesta:

Resolvemos:

a. (9+4m)^{2} = 9^{2} +2*9*4m+(4m)^{2} = 81+64m+16m^{2}  

b. (x^{10} +5y^{2} )^{2} = x^{20} +2* x^{10}*5y^{2} +25y^{4}  

x^{20}+10x^{10}y^{2}+25y^{4}    

c. (2x+3z)^{2}=(2x)^{2}+12xz+(3z)^{2} = 4x^{2} +12xz+9z^{2}    

d. (4m^{5}+5n^{3} )^{2} =(4m^{5} )^{2}+2*4m^{5}*5n^{3} +(5n^{3})^{2}      

16m^{10}+40m^{5}n^{3}+25n^{6}
