Move to constant to right side
Make the logarithm disappear by making both sides an exponent of 10
Simplify the right

Given: #log_10(x) - 2 = 0#

Move the constant to the right:

#log_10(x) = 2#

Make the logarithm disappear by making both sides the exponent of 10:

#10^(log_10(x)) = 10^2#

#x = 10^2#

Simplify the right:

#x = 100#
