Simplification of algebraic formula. (a+b)^3
Basic way: (a+b)^3=(a+b)*(a+b)*(a+b) or, (a+b)^3= (a+b)*(a(a+b)+b (a+b)) or, (a+b)^3= (a+b)*(a^2+ab+ba+b^2) or, (a+b)^3=(a+b)*(a^2+2ab+b^2) or, (a+b)^3=a(a^2+2ab+b^2)+b(a^2+2ab+b^2) or, (a+b)^3=a^3+2a^2b+ab^2+a^2b+2ab^2+b^3 or, (a+b)^3=a^3+3a^2b+3ab^2+b^3 (a+b)^3-3a^2b-3ab^2=a^3+b^3
Importance of civil engineering projects in the society?
Civil engineering are the fundamental of any development. It is the primitive and governing engineering of all. From the house we live, food we eat, transportation, utility buildings like hospital, school, offices, bridges almost everything is constructed by the utilization of the civil engineering knowledge. Everything is connected with civil engineering.
What are the general real challenges in the site for roadway construction?
