How do I put log in a TI-84 calculator.
#1.Express the logarithm in terms of log2M and log2N:
log2(MN)4

#2. Express the logarithm in terms of log2M and log2N:
log2 the cube root of M2N

#3. Express the logarithm in terms of log2M and log2N:
log2 (M/N)7

#4. Express the logarithm in terms of log2M and log2N:
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

    In my Ti83 you have your choice of log key which is log base ten and ln key which is log base e
    1.
    log (4 M N) = log 4 + log M + log N
    or perhaps you mean
    log (MN)^4
    which is
    4 (log M + log N)

    2.
    do you mean M^2 N ????
    (1/3)(2 log M + log N)

    3.
    (1/7) (log M - log N)

    These are all the same. I am bored.
