Math help plz
Given that 4^x=N, express 8^x in terms of N.

4^x = n
log (4^x) = log (n)
log (4)^x = log (n)
x log (4) = log (n)
x = ( log (n) ) / ( log (4) )
x = log (n - 4)
8^x = 8 ^( log (n - 4) )
log (4^x) = log (n)
log (4)^x = log (n)
x log (4) = log (n)
x = ( log (n) ) / ( log (4) )
x = log (n - 4)
8^x = 8 ^( log (n - 4) )
