Помогите плиз с алгеброй

Answer 1

Объяснение:

6/8

$1-x^{54}d^{18}=1^2-(x^{27}d^9)^2=(1+x^{27}d^9)*(1-x^{27}d^9).$

7/8

$m^6+0,027n^3=(m^2)^6+(0,3n)^3=(m^2+0,3n)*(m^4-0,3m^2n+0,09n^2).$

8/8

$(t^{10}+m^{10})^2-(t^{10}-m^{10})^2-t^2m^2=\\=(t^{10}+m^{10}+t^{10}-m^{10})*(t^{10}+m^{10}-t^{10}+m^{10})-t^2m^2=\\=2*t^{10}*2*m^{10}-t^2m^2=4*t^{10}m^{10}-t^2m^2=t^2m^2*(4t^8m^8-1).$

3/8

$0,25m^{14}n^{14}k^{18}=(0,5m^7n^7k^9)^2.$
