As you have to reverse the direction of the inequality when dividing by negative numbers
Hello
I have an inequality where I have this equation:
0.79^n < 0.1
I assumed that if I take logs of both sides the result would be:
n log 0.79 < log 0.1
n < log 0.1 / log 0.79
n < 9.768
But actually result should be n > 9.768
Why is the inequality symbol reversed in this situation?
