**Logarithmic and Power functions in python for data science:**

**exp(a) –**When this function is called, it returns the value of ‘e’ raised to the power**‘a’ (e**a)**.**log(a, b) –**This function will return the logarithmic value of ‘a’ with base ‘b’. In the case base is not mentioned, then natural log is computed.

** **

**log2(a) –**This function is there when we need to compute value of log ‘a’ with base 2. This value is more accurate than the log function.**log10(a) –**This function is there for computing value of log ‘a’ with base 10. The value returned is more accurate than values returned by the above functions.

** **

**pow(a,b) – I**t is there for computing value of ‘a’ raised to the power ‘b’ (a**b).**sqrt() –**This is there to return the square root of a number.
