Answer 1

$-0,2a^2bc^8(-3b^5c^3)=0,6a^2b^{1+5}c^{8+3}=0,6a^2b^6c^{11}\\\\(-2n^4)^5=(-1)^5*2^5n^{4*5}=-32n^{20}\\\\(-0,6c^5x^2)^3=(-1)^3*(0,6)^3c^{5*3}x^{2*3}=-0,216c^{15}x^6\\\\5am^7n^3*(-0,7a^9n^4)^2=5am^7n^3*(-1)^2*(0,7)^2a^{9*2}n^{4*2}=\\\\=5am^7n^3*1*0,49a^{18}n^8=2,45a^{1+18}m^7n^{3+8}=2,45a^{19}m^7n^{11}\\\\(c^{8-p})^3:c^5=c^{24-3p}:c^5=c^{24-3p-5}=c^{19-3p}$
