How do you find the inverse of #y = log_5x#?

3 Answers

The inverse is #y^-1=5^x#

Explanation:

It is #log_5 x=y=>x=5^y=>y^-1=5^x#

#x= 5^y#.

Explanation:

Raise both sides to the power of 5.
#m^(log base m# is like 'sin arc sin' operator that is the operation, in succession, with 'an operator and its inverse'.
Logarithmic function is the inverse of power function of the base. For example, #lne^n# = n.and #e^lnm#.= m.

The answer is #log_x5#

Explanation:

Here #y=log_5x#
#:.# inverse of y = #1/y=1/(log_5x)=(cancel(log_5x)*log_x5)/cancel(log_5x)=log_x5#

Is it correct?
