integral from 2 to 5 of 1/((5x-20)^3)

\int_{2}^{5} \frac{1}{( 5 x - 20 ) ^{3}} d x

diverges

Solution steps

\int_{2}^{5} \frac{1}{( 5 x - 20 ) ^{3}} d x

Find undefined (singularity) points:

x = 4

If exist

b, a < b < c, f (b) =

undefined

, \int_{a}^{c} f (x) d x = \int_{a}^{b} f (x) d x + \int_{b}^{c} f (x) d x

= \int_{2}^{4} \frac{1}{( 5 x - 20 ) ^{3}} d x + \int_{4}^{5} \frac{1}{( 5 x - 20 ) ^{3}} d x

\int_{2}^{4} \frac{1}{( 5 x - 20 ) ^{3}} d x =

diverges

If part of the expression diverges, then entire expression diverges

= diverges
