Q. What is y = 4 log 2x equivalent to?


y = log 4x2
y = 4 log 8x2
y = log 8x
y = log 16x4
Q. What does log -1 equal?


0

Q. What is


y = ln x + ln y + ln z
y = -ln x + ln y – ln z
y = ln x + ln y – ln z
y = -ln x + ln y + ln z
y = ln x – ln y – ln z
Q. What is y = log4 (x + 2) + log4 16 equivalent to?


y = log4 (4x + 16)
y = log4 (16x + 8)
y = log4 (2x + 4)
y = log4 (16x + 32)
y = log4 (x2 + 16)
