Evaluate the integral
x4(x510)26dx\displaystyle \int{x}^{{4}}{\left({x}^{{5}}-{10}\right)}^{{{26}}}{\left.{d}{x}\right.},
by making the appropriate substitution: u = .
 

x4(x510)26dx\displaystyle \int{x}^{{4}}{\left({x}^{{5}}-{10}\right)}^{{{26}}}{\left.{d}{x}\right.} =
 

NOTE: Your answer should be in terms of x\displaystyle {x} and not u\displaystyle {u}.
