We understand that 2^6=2x2x2x2x2x2. Express 2^6 in terms of 2+2a+2b+c.FInd the value of a,b and c.?

U can solve this question by using Binomial Theorem.

i dint get u if u want to find the possible values of the expresion then dere r many ways u can get the value of a,b,c if u substitute a=14,b-15 and c=4 u will get 64 dats 2^6 .. wat exaactly do u want
Reply:IT IS 64.IF C=2 , 2a+ 2b+2=62,.a+b+1=31,a+b=30


give any value to a and b
Reply:assuming a,b,c are positive.





2+2a+2b+c=64,


2a+2b+c=62


2(a+b)=62-c


c cannot be an odd number because then 62-c is odd and 2(a+b) has to be an even number.


so, if c=0, a+b=31 , from a=0 to a=31, there are 32 possible combinations


if c=2, a+b=30, again a=0 to a=30, gives 31 combinations.


and so on, if c=62, a=0,b=0





so there are 32 possible values of c of even numbers from 0 to 62





if negative numbers are allowed, then we have infinite possibilities for a,b,c
Reply:this is your home work just do it your self if you don,t know then i will do it .if you don,t know then better keep on practice
Reply:2^6=2x2x2x2x2x2=64





2+2a+2b+c=64


2a+2b+c=64-2


2a+2b+c=62


2a+2b+c=62


2(a+b)=62-c





damn, i'm confused..., i give up
