Abb kyu padh rha
Advanced ho to gaya
my approach
hume 11th me limits padha rahe in basic maths
243 = 3⁵
27 = 3³
Accha tu alag sidd hai ☠️ my bad sorry
sqrt makes it half the exponent
So standard
(x^m-a^m)/(x^n-a^n)
Oh yeah calculation mistake
(m/n)(a^(m-n))
27 is 3 ka cube na
5 should be the answer
Let me try again
Option D is 5 I'm guessing
If you can't remember this form, remember x^n-a^n/x-a = na^(n-1)
Multiply and divide by x-a. Split the limit. You'll get one in standard form and one as reciprocal. Multiply again.
Kuch nahi yaad rehta hai toh L'Hôpital is your friend
way too many people named sidd fr
n is 3/2 not 1
yea wait
Aur (5/2)/(3/2) = 5/3
My Hindi is bad. I'll stick to English.
its 5/2)/(3/2)(x)
Iske aage kya karu
Nope. Wait I'll write and send
Ye wala result nahi padhaya hume
So agar niche bhi power hoti hai to aise karte hai
Ignore the organic chem question. I couldn't bother to crop it out.
Ya bro got it. Thanks for the derivation also.
Bro any idea about 14 and 15?
I tried using trigonometry in the 14th question but it all got messed up
Fifteenth is easy
Fourteenth one LDNE I think.
You took LHL here?
Yup. One is -∞ and the other is +∞
