LOGARITHMS 1



Evaluate Log2(2048 x 16).

Solution

= Log2(2048 x 16)

= Log22048 +  Log216          (applying the product rule)

= Log2211 +  Log224             (2048= 211 and 16=24 )

= 11Log22 +  4Log22       ( remember  Logaac = cLogaa )

= (11 x 1) +  (4 x 1)          ( remember  Logaa = 1 )

= 11 + 4

= 15

hence Log2(2048 x 16) = 15

TRY THIS………………


Evaluate Log2(32 x 256).
