Use should put a couple of these scales on some plastic strips that you can move back and forth and then you could do multiplication without worrying if the batteries are going dead! ;-)

@kenufak 10^1/2 is just root 10...which is not futher reducible

10^x = 2, take the log of both sides

log 10^x = log 2

using log rule simplify the x down

x log10 = log2

x = log2 / log10

@edwardmeade It's called a slid rule

@Rardon99 that is a good question. It would in theory be an infinite amount to the left of your paper. But of course that doesn't exist ... no zero or negative numbers on log scale :)

10^0 = 1

I think you put 1 on the number scale because if you put 0 you would have got 1 whenever you raised a number to any power.

i think this would help my whole maths class understand logs better.
