Remember that x^(-1) = 1/x
Also remember that x^0 = 1
so 4^(-3) = 1/(4^3)
can be rewritten as 1/16
can you take it from there?
3^(2x+1-x+2)=3^(x2-x) take log_3 of both sides to render the equation
2x+1-x+2 = x2-x, did you mean x^2 instead of x2 anyway you can take it from here I'm sure.
BTW we usually use * for multiply to avoid confusion with the variable x
you can also learn latex and write stuff like this
