For the 3rd black box, go to expanding expanding logs to see it solved

Unsolvable Algebraically

pH scale

pH=-log[H^+]

pH > 7 basic

pH < 7 acidic

Small basic - 7 - big acidic

.

Richter scale

*rewrite notes, this is hardest

.

Note: watch for the units of input and output. Sometimes they can be in billions or really small numbers

Note2: don’t be afraid to solve for variables then plug everything in

Note3: substition is a great way to track tricky decimals
