How do I put log in a TI84 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.
