Question 1198773
loga(x + 1) - loga(4) is equal to loga((x+1)/4)


when a = 10, you get log10(x+1) - log10(4) = log10((x+1)/4) which is equal to log((x+1)/4) on your calculator.


to confirm, get the result of log(x+1) - log(4) and then compare it to the result of log((x+1)/4)


they should be the same.


take any random value of x that will give you a real answer.
x = 27 will do.
log(28) - log(4) = .84509804
log(28/4) = log(7) = the same.


this confirms that loga(x+1) - loga(4) is equivalent to loga((x+1)/4)
