log2 1/MN

#5. Simplify:

log4 3 - log4 48

#6. Solve the equation:

loga x = 3/2loga 9 + loga 2

#7. Solve the equation:

logb (x2 + 7) = 2/3logb 64

#8. Solve the equation:

loga (3x + 5) - loga (x - 5) = loga 8

log4(3)-log4(48) = log4(3/48) = log4(1/16) = log4(4^-2) = -2

loga(x) = 3/2 loga(9) + loga(2)

loga(x) = loga(27*2)

x = 54

logb(x^2+7) = logb(16)

x^2+7 = 16

x^2 = 9

x = ±3

loga(3x+5)-loga(x-5) = loga(8)

loga((3x+5)/(x-5)) = loga(8)

(3x+5)/(x-5) = 8

x = 9
