#x=e^(-27/10)=x#

After5 the Definition

#log_a(b)=n# if #a^n=b#
we get

#log(x)=-27/5#
therefore

#x=e^(-27/5)#

#~~3.98*10^-6#

Given: #-log(x)=5.4#

#=>log(x)=-5.4#

Since there is no base, the assumed base used is base #10#.

So, we get:

#log_10(x)=-5.4#

#x=10^-5.4# (through logarithm definitions)

#~~3.98*10^-6#
