15th one is case-working: Make two cases, one where $(2x-3) \in (0,1)$ and one where 2x-3>1
SirLancelotDuLac
wait its greater than 1
or not equal to one
its greater than 0
greater than 1 see graph of log
oh damn mai case hi galt bana raha tha
maine bhi ek hafte phele hi kiya tha revise usse phle same misktate lmao
Black Book?
The 16th one is someting like this: [logn]=P has how many solutions? All the numbers from 10^P to 10^(P+1)-1
Similarly for [-logn]=-q, the value of n must be from 10^(q-1)+1 to 10^q
So you get the number of solutions and hence the answer.
17th one just asks (the number of digits in 2^2010)-1 if I'm not wrong.
So, that you can get by the finding characteristic method as [2010log2]+1
what how??
HUH???
thats acc pretty smart
log(x) is a increasing function right? (btw base is 10, too lazy to use latex bot) So, when do you get log(x)=p? 10^p Now when do you get log(x)=p+1? 10^(p+1), so all the numbers from 10^p to 10^(p+1)-1 have log with g.i.f value as p.
Or you could also see it by the number of digits.
For the q one in 17th, the range would be 10^(q-1)+1 to 10^q sorry.
broo GIF kaha se aaya
Characteristic of a number means $[log_{10}n]$ no?
SirLancelotDuLac
And mantissa is the fractional part of the same.
whatttt
WAHTTTT
THIS IS NEW
NO WAY
INSANE BHAI
Characteristic gives you information about the number of digits in a very large number (like in 18th)
i had no idea
where can i learn nmore about this
I think it was in f.o.m. if I'm not mistaken...
ab ye kya
f o m
The first chapter in maths in 11th. Basics of math or Fundamentals of Maths. I think uski module mein hi tha...
what
usme ye to nahi bataya tha yes GIF wagera padha tha but not this
ok leave it its GIF got it
never knew about this but THANKSS
what book is this
The coaching module.
Not a text book.
damn which coaching
Resonance.
ic
yeah it doesnt directly come in jee
