find the value of log40 1000÷log40 100
Answers
Step-by-step explanation:
log10(x) = y is equivalent to x = 10y
Common log is also written without the base 10,
log10(x) = log(x)
x: is real number, x>0
Common Logarithm Examples
Using logarithm of a product identity to find common log of 120:
log(120) = log(100 × 1.2)
log(120) = log(100) + log(1.2)
log(120) = 2 + 079181246 = 2.079181246
Using logarithm of a power identity to find common log of 106:
log(106) = 6 × log(10)
log(106) = 6 × 1 = 6
