Logarithms Calculation formula
log100(5)=loge(100)loge(5)
100base and number 5 logarithms calculation example
Now, we will understand logarithms and logarithm calculation. For this, we take an example. Calculate the 100 base and number 5 logarithms calculation. Calculate the natural logarithm (loge) of the number 5:
loge(5) = 1.609
Calculate the natural logarithm (loge) of the base 100:
loge(100) = 4.605
Divide the result from step 1 by the result from step 2:
log100(5) = 4.6051.609 = 0.3495
So, The correct value for log100(5) is approximately 0.3495.
