log5+%2816%29-log5+%282t%29=log5+%282%29
Recognize that the left side can be re-written according to an algebraic
property of logarithms:
log5+%2816%2F2t%29=log5+%282%29
This now allows you to rewrite the equation with each side being the
exponent of 5 without changing the value of the equation:
5%5E%28log5+%2816%2F2t%29%29=5%5E%28log5+%282%29%29
This form now allows you to use one of the inverse properties
of logarithms to re-write the equation as follows:
16%2F2t=2
Then just solve for t:
16=4t
t=4
