Integrate with respect to x :

Question

∫3−1x7+x2−−−−−√dx

Answer 1

Try writing the fraction like this

(3-x^7)/√(7+x^2) dx

or something. I can't parse your text. I just know that √dx is meaningless, so your fraction is garbled. Use "/" for fractions, as formatting in the browser is problematic at best.
