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

y = log(4x2)
y = 4log(8x2)
y = log(8x)

Q. What is equivalent to?

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 = 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)
