Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Take x common and take it inside the fractional powered polynomial it will become x^3 and then substitute the thing inside
Wow
Socha kaise bhai ye
Kya strike kara
rawdogging questions i suppose
Mostly experience but if you were to get it the first time the thought process would be to make the derivative of the polynomial inside match the outside stuff
Yea i was thinking ki derivate karke andar vali cheez bnje par ye nahi aaya tha dimag mein
Thanks tho
Ek ye bhi dekhlo
3rd one
Try messing around take something common send it inside or outside thats how you learn this chap
Alright
I tried lnx ko t substitute karke
Usse t/root1+t aagya
Send one x from the outside to the ()^1/3 wala term
Tbh bhai ye dimaag me aram se aayega bhai meko dekhte hi aagya cause I had done this type of ques by myself earlier
Uske baad substitute whatever is inside the ()^1/3 term
Is the ans A ?
$\int{(x^{7}+x^{5}+x^{2})(3x^{8}+4x^{6}+8x^{3})^{\frac{1}{3}}dx}$ Substituting $3x^{8}+4x^{6}+8x^{3}=t$ you find the answer

Okay, I did not read the thread mb.
Yes
DwðŸ˜
Its fine :Rick_cool_smug:
Ok so try substituting the things you dont like in these kinds of questions
Like (1+lnx)^1/2 here
Isko substitute karun?
Ajib ha
Yeah
Ab karlunga chalo
Try and ping me if you don't get
