The value of $∫(5x-2)^3dx$ is :

$3(5x-2)+C; $ C is constant of integration $15(5x-2)^2+C; $ C is constant of integration $(5x-2)^4+C; $ C is constant of integration $\frac{(5x-2)^4}{20}+C; $ C is constant of integration

$\frac{(5x-2)^4}{20}+C; $ C is constant of integration

$∫(5x-2)^3dx$ $=\frac{1×(5x-2)^{3+1}}{5×(3+1)}+C$ $=\frac{(5x-2)^4}{20}+C$ Using $∫(ax-b)^ndx=\frac{(ax-b)^{n+1}}{a×(n+1)}+C$
