• formulas
log m+ log n = log mn
log m- log n = log m/n
log mⁿ = n log m
log base mⁿ (X) = 1/n log base m (X)
log base b (c) = log c /log b
• important points
if number of log can be only greater than 0
base of log can be greater than but can not equal to 1
log 1 = 0
if base greater than one and number greater than one then value of log will be positive
if number less than one
base greater than one than log will be negative
if number less than one base less than one then value will be positive

log m- log n = log m/n
