f\left( {x + y} \right) = 2f\left( x \right)f\left( y \right),f'\left( 5 \right) = 1024\left( {\log 2} \right)

and

f\left( 2 \right) = 8,

then the value of

f'\left( 3 \right)

View answer and explanation

Correct option: A

64\left( {\log 2} \right)

Option A (

64\left( {\log 2} \right)

) is correct because it is the value of

f'(3)

obtained after using the given functional equation and derivative information.
