Do you have to simplify the exercice(s) with the exponents?
For the logarithmic equations, use:
For example the second one:
(and offcourse if you want to do the solution check: )
I have four problems I need help on:
(I believe it's multiplying, the copier messed up)
(It's log Base 5, as in the 5 there should be below the rest of the equation)
(This is base 10)
Right! and are indeed the solutions (don't forget to check them!)
But your first exercice is not clear, because you're not using brackets.
I guess you've to simplify:
(to simplify, look at the 'basic rule' I gave in one of my previous posts)
