A. 4
B. 0
C. 8
D. 1

Answer 1

draw it out

Answer 2

u tried ? what u got ?

Answer 3

nopes, use this property
\(\huge n^{\log_na}=a\)
or do u need to prove it ?

Answer 4

@hartnn right... :)

Answer 5

sure, taking log on both sides,
(log_n a) log n =log a
(log a)/(log n) * (log n) = log a
log a =log a
so that is an identity.

Answer 6

then just put n=4,a=8

Answer 7

u would understand that only if u know the properties of logarithms....
