WebTo get the logarithm with a custom base using numpy.log: import numpy as np array = np.array ( [74088, 3111696]) # = [42^3, 42^4] base = 42 exponent = np.log (array) / np.log (base) # = [3, 4] Which uses the logarithm base change rule: Share Improve this answer Follow edited Feb 26 at 1:10 answered Aug 6, 2014 at 20:09 dwitvliet 7,064 7 36 62 22 Web6 aug. 2010 · You can therefore replace the logarithm in a base by the logarithm in another base just by multiplying by that constant. Ex. You display the trendline equation in the chart: y = 675.489569563135 * ln(x) - 224.580147323782 We know that ln(x) = ln(10) * log(x) = 2.30258509299405 * log(x) Replacing, we get y = 1555.37221334904 * log(x) - 224. ...
