The integral equals #x^4 + C#

Explanation:

As given by the power rule, #int x^ndx = x^(n + 1)/(n + 1)#.

#I = 4x^(3+ 1)/(3 + 1) = x^4 + C#

Hopefully this helps!

#\int 4x^3 dx= x^4 + C#

Explanation:

#\int 4x^3 dx#

#=4(x^(3+1)/(3+1))+C# ; #C\equiv# arbitrary constant

#=4(x^(4)/(4))+C#

#= x^4 + C#
