Question

integrate x ^(-7) dx

Answer 1

use the standard result
\(\huge \int x^ndx = \dfrac{x^{n+1}}{n+1}+c\)

Answer 2

here, n = -7

Answer 3

-(1/6) x^-6

Answer 4

correct :)

Answer 5

but isn't it if you integrate 1/x = ln|x|?

Answer 6

a little confused because the original problem can be written as 1/x^7

Answer 7

it can be written,
but to be able to use standard formula, you'll have to write
1/x^7 as x^-7 again :)

Answer 8

ok
