1. hi, was wondering if someone could explain how this website has gone from (log4(x+1))/2 to log4((x+1)^1/2)

my teacher wasnt here for the lesson so i had to self teach. i understanfd the actual change of base formula, i just dont understand the bit above, feel like im missing something really obvious haha

thanks

hi this is a simple case of xloga = loga to power of X rule. the log4(x+1)/2 is the same as 1/2Xlog4(x+1) which = log4(x+1) to power of half
