Question

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

Answer 1

did u try taking log on both sides ?

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

b=2 will give you the required simplification

Answer 9

^ in the exponent , change b to 2

Answer 10

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

Answer 11

@rsadhvika how can i myself assume b=2

Answer 12

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