(a)^(4-x) . (b)^(4x) = (a)^(x+b) . (b)^(2x) prove that x log(b/a)=log (a)

hartnn (hartnn):

did u try taking log on both sides ?

OpenStudy (anonymous):

yes....but i am not getting answer of this form...

hartnn (hartnn):

are you sure its a^(x+b) ?? that b shouldn't be there..

OpenStudy (anonymous):

yes..it is a to the power x+b

hartnn (hartnn):

if the exponent hass b then it is impossible to prove that

OpenStudy (anonymous):

thats what i am trying.....but couldnt prove

OpenStudy (rsadhvika):

(a)^(4-x) (b)^(4x) = (a)^(x+2) (b)^(2x)

OpenStudy (rsadhvika):

b=2 will give you the required simplification

OpenStudy (rsadhvika):

^ in the exponent , change b to 2

hartnn (hartnn):

that must be it that should be x+2 not x+b

OpenStudy (anonymous):

@rsadhvika how can i myself assume b=2

OpenStudy (rsadhvika):

i think some pondering over the solution... and not getting it quite, and seeing it in multiple angels.. tells thats a typo :)
